Understanding Your Acura’s Roof & Cargo Box Basics

Okay, before we start shouting out specific boxes, we gotta lay down the groundwork. Not all Acura roofs are created equal, and slapping any old box up there is a recipe for headaches – or worse, damaged paint or a flying suitcase scenario. No way! First things first: what kind of roof do you have?

• Factory Roof Rails: You see those bars running front-to-back along the edge of your roof? That’s awesome! Many MDX, RDX, TLX, and older ILX/RLX models come with these standard or as an option. These rails are the anchor points. But hold up – you usually still need crossbars! Think of the factory rails as the side tracks; the crossbars are the actual beams that span across the width of the car, providing the mounting surface for the cargo box. Choosing the right crossbars compatible with your specific Acura’s rail system is step one. Getting the wrong fit is a total bummer and can be unsafe.
• Bare Roof (Flush Rails): Looking at a smooth, sleek roof on your Integra, TLX, or NSX? No visible side rails? This means you likely have mounting points hidden under little plastic covers along the roof’s edge. To mount anything up top, you absolutely need a dedicated roof rack system designed specifically for your car’s year and model. This system includes both the feet that clamp onto those hidden points and the crossbars. Skipping this step isn’t an option. Trying to rig something else is a massive risk and will almost certainly damage your paint. For real?
• Fixed Point Crossbars: Some newer Acuras (especially certain RDX and MDX trims) might come with fixed crossbars already installed as part of a roof rail system. That’s super convenient! You can often mount a box directly to these, but always double-check the weight limits and compatibility with your chosen box’s mounting system. Don’t just assume.

Weight Limits Aren’t Just Suggestions!

This is crucial, folks. Every Acura has a maximum roof load capacity, and every cargo box has its own weight rating (both the box itself and how much gear it can hold safely). Exceeding your vehicle’s limit is dangerous – it stresses the roof structure, messes with handling, and is just plain risky. You’ll find this info in your owner’s manual – seriously, dig it out or look it up online for your exact year and model. Ignoring this is playing with fire. How terrible would it be to cause damage or an accident just because you overloaded the roof?

Generally, Acuras range between 165 lbs for something like an NSX up to around 165-220 lbs for larger SUVs like the MDX. Remember, this total includes the weight of the cargo box itself plus everything you put inside it! A heavy-duty box might weigh 50-60 lbs empty, leaving you only 105-165 lbs for your gear on many models. That adds up fast with bulky items like camping chairs or duffel bags. Off the top of my head, that’s maybe 3-4 decently packed suitcases max, depending on the box and car.

Aerodynamics & Noise: Keeping the Acura Vibe.

You bought an Acura for its smooth ride and refined feel, right? Whistling, booming, or a huge hit to your gas mileage from a poorly designed roof box totally sucks the joy out of a road trip. Modern cargo boxes are lightyears ahead of the old-school clunky ones. Look for sleek, aerodynamic shapes (teardrop profiles are gold), textured surfaces to reduce wind noise, and features like integrated vortex generators. While any box will have some impact on fuel economy (expect maybe a 1-3 MPG drop, sometimes more at high speeds), a well-designed one minimizes the drag. You shouldn’t feel like you’re suddenly driving a barn door. Choosing a box that complements your Acura’s lines isn’t just about looks; it’s about preserving that driving experience you love.

Top Contenders: Brands & Models Acura Owners Love

Alright, let’s talk boxes! While many brands exist, a few consistently rise to the top for Acura owners, offering the perfect blend of quality, fit, features, and that essential Acura-level refinement. Totally legit choices include:

1. Thule Motion Series (XT, XL, L, etc.): Dude, these are everywhere for a reason. Think of them as the Swiss Army knife of roof boxes – super versatile, reliable, aerodynamic, and look sharp on everything from an MDX to an Integra. The Motion XT has a more squared-off front for max cargo space (awesome for bulky items), while the standard Motion 3 is sleeker. They feature Thule’s awesome QuickGrip knobs for super easy mounting and removal – seriously, it takes minutes once you get the hang of it. Dual-side opening is standard, so you can access your gear from either side of the car, which is super handy in tight parking spots. They’re tough, secure with integrated locks, and just work. For real, it’s hard to go wrong with a Motion box. Wondering how different sizes stack up? Check out how the Motion 3 L compares to the XL or even the Motion XT L.
2. Yakima SkyBox Series (Carbonite, NX, LoPro): Yakima is another giant, and their SkyBox line offers fantastic alternatives. The SkyBox NX is super popular, known for its clean lines and low profile, blending seamlessly with your Acura’s roof. The SkyBox LoPro lives up to its name, sitting incredibly low for garages or low-clearance adventures. Yakima boxes often feature their SKS Locks (one key fits all locks on the box and compatible Yakima racks – super convenient!). They’re also known for robust construction and excellent weather sealing. If you’re tight on height or just want the sleekest look possible, Yakima is a top contender. Curious how the skinny SkyBox NX Skinny compares to Thule? We’ve got you covered right here.
3. SportRack Vista Series: Looking for fantastic value without sacrificing core features? SportRack (often found at places like Rack Outfitters or major retailers) is worth a serious look. The Vista XL offers a massive amount of space at a price point that’s easier on the wallet than the premium brands. Don’t mistake “value” for “cheap” though – they feature dual-side opening, decent aerodynamics, and integrated locking systems. They might be a bit heavier or have slightly less refined finishes than Thule/Yakima, but for the price, they deliver serious bang for the buck. Wondering how the Vista XL stacks up against a Thule Force? This comparison breaks it down.
4. Thule Force Series (XT, L, etc.): A slightly more budget-friendly line from Thule compared to the Motion, the Force series is still incredibly capable. They often have a slightly more angular shape than the Motion but still offer great features like dual-side opening, easy mounting systems, and good security. They provide excellent capacity and durability. The Force XT offers that squared-off front for max volume. If you want the Thule reliability but need to save a few bucks, the Force is legit. Get the full scoop on the Thule Force 3.
5. INNO Wedge & Shadow Series: Offering a unique, super-sleek aesthetic often at a competitive price, INNO boxes are gaining fans. The Wedge has a distinctive shape designed for maximum aerodynamics, while the Shadow offers a more traditional but still low-profile look. They often include cool features like reinforced lids you can stand on (handy for accessing gear or securing loads) and tool-free mounting systems. If you want something that stands out a bit from the crowd with great performance, check out INNO. See how they fit into the bigger picture of best cargo boxes.
6. Tuffiom: This brand is making waves with durable boxes featuring scratch-resistant textures and robust construction, often at very attractive prices. They focus on practicality and toughness, offering spacious interiors and user-friendly features. If you prioritize ruggedness and value, Tuffiom is definitely worth exploring.

Key Roof Cargo Box Features & Specs

Finding the Perfect Box for YOUR Acura Model

Alright, let’s get specific! While many boxes can fit various models (with the right rack!), some considerations are unique to each Acura’s shape, size, and roof type. Let’s break it down:

Acura MDX: The Family Adventure Machine

How’s it going, MDX owners? You’ve got the space… until you don’t! Road trips with kids, sports gear, or camping equipment can quickly overwhelm even the MDX’s generous cargo hold. A roof box is practically essential gear. The MDX’s roof is spacious and strong, usually rated around 165-220 lbs total capacity (box + gear). You’ve got options!

• Max Capacity Kings: Need to haul everything? Look at the biggest boxes: Thule Motion XT XL (18 or 21 cu ft), Yakima SkyBox 21 Carbonite, or the SportRack Vista XL (18 cu ft). These beasts swallow strollers, coolers, duffel bags, and bins with ease. Perfect for cross-country trips or large families. The squared-off front on the XT XL or Vista XL maximizes that volume. Explore specific options perfect for the MDX.
• The Balanced Approach: If you don’t always need max capacity but want great aerodynamics and a sleeker look, the Thule Motion 3 L (16 cu ft) or Yakima SkyBox NX 18 (18 cu ft) are stellar choices. They offer plenty of space for most needs while minimizing wind noise and fuel impact. The SkyBox NX’s low profile is particularly nice.
• MDX-Specific Tips: Pay close attention to sunroof clearance! Measure the space between your crossbars carefully, ensuring the box won’t block a panoramic roof or interfere with the antenna. Most modern boxes have cutouts, but double-checking is key. Also, factor in garage height if you park inside – a taller box on an already tall SUV might not fit.

Acura RDX: Sporty Utility Unleashed

RDX crew, what’s new? You love that blend of performance and practicality. But even the RDX’s cargo area can feel tight with active lifestyles – bikes, skis, or weekend getaway gear need room! The RDX roof is robust, typically rated for 165 lbs total load. Its slightly shorter roof than the MDX means sizing is crucial.

• Sweet Spot Sizing: The Thule Motion 3 L (16 cu ft) and Yakima SkyBox 16 Carbonite are often considered the perfect fit for the RDX. They offer substantial space (enough for 4-6 large suitcases equivalent) without overwhelming the vehicle’s lines or creating excessive overhang. They maintain the RDX’s sporty aesthetic.
• Low Profile Lovers: Want the box to almost disappear? The Yakima SkyBox LoPro series is designed to sit incredibly low, minimizing wind noise and drag even further. It’s a fantastic choice if you prioritize fuel economy and a stealthy look. The Thule Force L is another great, slightly more affordable option that fits well.
• RDX-Specific Tips: Like the MDX, sunroof clearance (especially panoramic roofs) is paramount. Measure meticulously! Also, the RDX’s rear hatch has a specific lift height – ensure the box doesn’t extend so far back that it prevents the hatch from opening fully. That would be a major bummer when unloading groceries! Get the lowdown on ideal RDX cargo carriers.

Acura TLX: Sophisticated Hauling

Alright TLX owners, how’s it going? You’re cruising in one seriously sharp sedan, we get it – but let’s be real, that trunk hits its max fast when you’re loading up for anything beyond daily drives. Weekend escapes, gear-heavy adventures? Suddenly you’re playing luggage Jenga instead of relaxing. For real, who needs that stress? Here’s the good news: throwing a cargo box up top solves your space crunch without trashing your ride’s sleek vibe. But first, gotta talk racks. See those smooth roof lines? Mounting points are hiding under little covers, so grabbing a rack system made specifically for your TLX’s year is absolutely non-negotiable. Skip the generic stuff unless you enjoy scratched paint and headaches. Oh, and that roof? It’s sturdy, but it’s not a dump truck – you’re looking at roughly 165 pounds total weight limit including the box itself. Keep that number front of mind!

So, you want that extra space but refuse to turn your head-turning TLX into a lumbering brick on wheels? Totally feel you. The secret sauce is nailing the look and the aerodynamics. Think low-profile ninjas, not bulky tanks. You want boxes that hug your roof tight and slice through the wind, keeping things quiet and efficient. Ditch the old-school clunkers! Check out gems like the Yakima SkyBox LoPro (comes in handy 13 or spacious 16 cubic foot sizes), the Thule Motion 3 (aim for the S or M, giving you 11 to 14 cubic feet), or the slick INNO Wedge 660 (13 cubic feet). These guys are designed to complement your car’s style, not clash with it. They’re basically the accessory your TLX didn’t know it needed.

Okay, let’s manage expectations. Your TLX isn’t an SUV, right? Its roof is shorter, so dreaming of those massive 18+ cubic foot monsters is a no-go. Nice try, but forget it. Focus instead on that sweet spot between 11 and 16 cubic feet. Honestly, that’s plenty smart for what you need! We’re talking multiple suitcases for a getaway, golf bags clattering around, or bulky-but-light stuff like camping gear or ski/snowboard bags. Ever tried stuffing all that in the trunk alone? Sucks. The roof box magic is about smart packing, not brute force hauling. It’s the perfect partner for your trunk, not a replacement. Wondering what fits other sleek sedans? Peek at ideas that work for the TLX too.

Listen up, because installation is where things get real. Getting the right rack system designed for your exact TLX year and generation is step zero. Trying to force-fit something else? Nice try, but you’re begging for roof dents or worse. Pay super close attention to where you place those crossbars – the distance between them (the “spread”) is crucial. Get it wrong, and your box might wobble like crazy, rub against your pristine roof, or smack your antenna. How annoying would that be? Taking the time to measure and mount everything perfectly isn’t just about safety (though that’s huge), it makes the whole setup look clean and professional. A messy install screams amateur hour and risks your paint. Give me a break – your TLX deserves better! Do it right the first time and cruise worry-free.

Acura Integra: Sporty Compact, Expanded Utility

Welcome back, Integra! The iconic nameplate is back, blending sporty fun with hatchback practicality. But even that hatch space fills up fast. Adding a roof box unlocks serious adventure potential while keeping the driving spirit alive. Like the TLX, you’ll need a specific roof rack system for the hidden mounts. Capacity is likely similar to the TLX, around 165 lbs.

• Compact & Aerodynamic is Key: With a compact roof, low profile and wind-cheating design are even more critical. Look for boxes specifically sized for smaller cars: Thule Pulse Alpine (11 cu ft – discontinued but found used, successor is similar Motion sizes), Thule Motion 3 S (11 cu ft), Yakima SkyBox LoPro 13 (13 cu ft), or the INNO Shadow 10 (10 cu ft). The new Thule Pulse might offer suitable sizes too.
• Volume vs. Vibe: You won’t fit a giant box, but 10-14 cu ft is surprisingly useful for luggage, skis/snowboards, or gear bags. It complements the hatch space perfectly for weekends away. The focus is on enhancing utility without turning your sporty Integra into a lumbering wagon. It should look like it belongs.
• Integra-Specific Tips: Precision rack fit is non-negotiable. Choose a system designed explicitly for the current-generation Integra. Measure carefully for overhang, especially at the rear, to ensure hatch clearance. The Integra’s sporty handling means keeping added weight and height as low as possible – stick to recommended capacities and low-profile boxes.

Acura NSX: The Exotic Exception

NSX owners, you absolute legends! How’s it going in supercar territory? We see you, and yes, even an NSX can technically use a roof box… though it’s definitely not the norm and requires serious thought. The NSX has an extremely limited roof load capacity – likely around 100 lbs or possibly less (consult your manual religiously!). The carbon fiber roof and exotic nature make this a unique challenge.

• Ultra-Light & Ultra-Compact ONLY: If you must add roof storage, it’s strictly for very lightweight, bulky items (think sleeping bags, empty duffels, maybe a tent). Forget large boxes. Look at the smallest, lightest options: Ski/Snowboard carriers (for specific gear) or the absolute smallest, lightest cargo boxes like the Thule Pulse S (approx 9 cu ft, ~25 lbs) or similar discontinued/ultra-compact models. Weight is the enemy here. Even a small box eats heavily into that tiny capacity.
• Serious Considerations: Aerodynamics: Crucial for high-speed stability. Noise: Any extra noise will be amplified. Rack Compatibility: Finding a rack rated safe for the NSX’s roof structure and weight limits is challenging and potentially expensive. Paint Protection: The risk of scratches is high; use extreme care and protection. Garage Clearance: The NSX is low; adding even a low-profile box might cause clearance issues. Honestly, for most NSX owners, renting a support vehicle or using creative packing inside is probably the more practical (and less stressful) route. Adding a box is a serious long shot and only for very specific, lightweight needs. It’s pushing the boundaries of the car’s design.

Acura ILX & RLX: Refined Sedan Solutions

ILX and RLX drivers, cruising comfortably! While these models might be less common now, the need for extra space still arises. Both typically have roofs requiring specific rack systems for hidden mounts. Roof load capacity is generally around 165 lbs, similar to the TLX.

• ILX (Compact): Follow similar guidance to the Integra/TLX compact size focus. Thule Motion 3 S (11 cu ft), Yakima SkyBox LoPro 13 (13 cu ft), INNO Shadow 10 (10 cu ft) are ideal sizes. Prioritize low profile and aerodynamic efficiency to complement the smaller car size. Focus on 10-14 cu ft capacity.
• RLX (Full-Size Sedan): Has a slightly longer roof than the ILX/TLX. You can potentially go slightly larger: Thule Motion 3 M (14 cu ft), Yakima SkyBox 16 Carbonite (16 cu ft), INNO Shadow 15 (15 cu ft) are good targets. Still prioritize sleek designs (14-16 cu ft) to maintain the RLX’s elegant profile. Avoid bulky, tall boxes.
• ILX/RLX-Specific Tips: As with other sedans, the correct, model-specific roof rack system is step zero. Ensure precise installation to avoid roof damage. Pay attention to crossbar positioning relative to the sunroof (if equipped) and the trunk lid opening arc. Measure twice, install once!

Acura ZDX: The Bold Crossover Returns

ZDX pioneers (and new ZDX EV adopters!), what’s up? Your unique, fastback crossover/coupe has distinctive lines and a sloping rear roofline. This presents specific challenges and opportunities for roof boxes. Roof load capacity is likely similar to the MDX/RDX, around 165-220 lbs, but the shape is key.

• Sloping Roof Challenges: The ZDX’s rear roof slope means a long box might overhang significantly at the back, potentially interfering with the rear hatch’s operation or simply looking awkward. It also limits the usable height towards the rear of the box.
• Smart Sizing & Positioning: Focus might shift towards slightly shorter boxes positioned more towards the front of the roof, where it’s flatter. This maximizes usable internal height. Models like the Thule Motion 3 L (16 cu ft), Yakima SkyBox 16 Carbonite (16 cu ft), or even a Yakima SkyBox LoPro 16 could work well, but placement is critical. Avoid very long boxes (like 18+ cu ft) that extend far back.
• ZDX-Specific Tips: Measuring is absolutely vital. Determine the maximum length you can use without the box hitting the rear hatch when it opens and without excessive overhang compromising the look or aerodynamics. Consult your manual for the exact roof load zones. Finding the right balance between capacity and the ZDX’s unique profile is key. Get insights tailored to the ZDX’s unique shape.

Buying, Installing & Using Your Acura Cargo Box Like a Pro

Alright, you’ve narrowed down your choices – awesome! Let’s talk about sealing the deal and getting that box up there safely and smartly. No big deal, right? Just a few more things to ace.

• Where to Shop & What to Look For: Major outdoor retailers (REI, Cabela’s, Bass Pro Shops), auto parts stores (sometimes), dedicated rack shops (like Rack Outfitters), and online giants (Amazon, eTrailer) are your main spots. Don’t just buy the first box you see! Check return policies in case the fit isn’t perfect. Look closely at warranty coverage – reputable brands offer decent protection. Read reviews, especially from owners with your same Acura model. Real-world experiences are gold. Ask about bundle deals if you still need the roof rack system too – you might save some cash.
• Installation: Getting it Right the First Time. Dude, this is crucial. A poorly installed box is dangerous and can wreck your roof. RTFM! (Read The Fantastic Manual!). Both the roof rack and the cargo box have specific instructions. Set aside dedicated time – don’t rush it in the driveway as it’s getting dark before your trip. You’ll grunt less, I promise. You’ll typically:
  1. Install the roof rack feet/crossbars following the vehicle-specific instructions meticulously. Torque bolts to spec! Over-tightening can damage mounts; under-tightening is unsafe.
  2. Position the box centrally on the crossbars. Measure the distance from each end.
  3. Attach the box clamps according to the box manual. Most modern systems use knobs or levers (Thule QuickGrip, Yakima’s system) – tighten them firmly and evenly.
  4. Double-check everything before loading. Give the box a firm shake – there should be minimal movement. Ensure clamps are fully engaged and locked if applicable.
  5. Consider having a pro install it the first time if you’re unsure. Peace of mind is worth it. Feeling under the weather about DIY? Totally get it.
• Packing Smart: Maximize Space & Safety. How you pack matters just as much as the box size!
  • Weight Distribution: Put the heaviest items over the crossbars, ideally centered between them. Avoid putting heavy stuff way at the front or back. This keeps the car balanced.
  • Fill the Gaps: Use soft bags (duffels, backpacks) that mold to fill spaces. Hard-sided suitcases leave awkward gaps. Pack clothes and lighter items around heavier gear to cushion it.
  • Secure Loose Items: Even inside the box, things can shift and bang around. Use straps, nets, or pack items tightly together. Don’t just toss stuff in!
  • Don’t Overload: Seriously, respect the weight limits! Weigh your gear if possible. Exceeding limits is asking for trouble. Remember the ROOF CAPACITY minus the BOX WEIGHT equals your MAX GEAR WEIGHT. Write it down!
  • Accessibility: Pack items you might need during the trip (snacks, jackets, diapers) towards the opening or on top. Opening the box at a rest stop shouldn’t require unpacking everything.
• Security & Peace of Mind: Most quality boxes come with integrated locks that secure the lid. Crucially, ensure your mounting system also locks the box to the crossbars (systems like Thule ClickLock or Yakima SKS do this with the same key). This prevents someone from just unclamping the whole box and walking off with it. While determined thieves can defeat anything, locked boxes are a strong deterrent. It’s not foolproof, but it’s way better than nothing. Give me a break if you think leaving it unlocked is fine!
• Maintenance & Storage: Treat your box right, and it’ll last for years. Give it a wipe down inside and out after trips, especially if it’s dirty or salty. Mild soap and water usually suffice; avoid harsh chemicals. Before storing it long-term (like over summer if you only use it for winter sports), make sure it’s completely dry inside to prevent mold or mildew. Store it somewhere cool, dry, and out of direct sunlight if possible – UV rays can degrade plastics over time. Many boxes can be stored vertically on end to save space in the garage (check your manual). Taking care of it means more adventures down the road.

Answering Your Top Acura Roof Box Questions (FAQs)

What size roof box do I need for my Acura?

Totally depends on your model and your needs! For MDX/RDX owners wanting max space, look at 16-21 cu ft boxes (Motion XT XL, SkyBox 21, Vista XL). For RDX/TLX/Integra, 14-16 cu ft (Motion 3 L, SkyBox 16) is often the sweet spot. For sedans/compact cars prioritizing looks, 10-14 cu ft (SkyBox LoPro 13, Motion 3 S/M) is ideal. Measure your roof’s usable length first! A box that’s too long won’t fit safely. Consider what you typically haul – are you packing for four people for two weeks, or just needing extra space for bulky sports gear? See how the Thule Motion 3 fits various cars for an idea.

Will a roof box fit with my sunroof?

Probably, but you must check! Most boxes need several inches of clearance above the sunroof glass to open and to prevent vibrations/rattles. Measure the height of your sunroof when fully open. Then, look at the box specifications for its “roof clearance” or minimum crossbar height needed. Also, ensure the box itself doesn’t physically sit on top of the closed sunroof glass – crossbars should be positioned so the box straddles the sunroof opening with ample space. When installing, open the sunroof before fully tightening the box clamps to guarantee clearance. Blocking your sunroof sucks the fun out of sunny drives.

How much does a roof box affect gas mileage?

Fair question! Any box adds drag, so expect a hit. How much? Off the top of my head, 1-5 MPG is common, depending heavily on the box (how aerodynamic it is), your car, your speed, and wind conditions. Driving 75 mph on the highway with a big, square box will hurt more than driving 55 mph with a sleek teardrop design. While it’s an extra cost, the convenience of carrying all your gear often outweighs the fuel expense for most travelers. Think of it as the price of adventure! Choosing an aerodynamic box like the Motion 3 or SkyBox NX minimizes the impact. See how the Motion 3 stacks up against competitors for efficiency.

Can I leave my roof box on all the time?

You can, but it’s generally not recommended for a few reasons. Fuel Economy: It will constantly reduce your MPG, even when empty. Noise: Even aerodynamic boxes add some wind noise. Wear & Tear: UV exposure and weather will degrade the box faster. Security: It’s more visible and could tempt thieves (though locked). Convenience: It adds height, potentially preventing you from entering garages or drive-thrus. Most owners install the box for specific trips (a few weeks or months) and remove it for daily driving. The good news? Modern mounting systems make install/removal pretty quick once you’ve done it a few times. It is what it is – a trade-off.

Are rooftop cargo boxes waterproof?

Most high-quality boxes (Thule, Yakima, SportRack, INNO) are designed to be weather-resistant, meaning they should keep out rain, snow, and dust under normal driving conditions. They use tight-fitting seals around the lid. However, calling them 100% “waterproof” is a bit of a stretch. In extremely heavy, driving rain or a torrential downpour while parked, some minor seepage might occur, especially at the seams or the latch areas over time. It’s not common, but it can happen. For real peace of mind with sensitive items (electronics, down sleeping bags, important documents), using waterproof stuff sacks or bins inside the cargo box is always a smart backup plan. Don’t tempt fate!

Time to Load Up and Hit the Road!

So, there you have it, Acura enthusiast! No more stressing about packing the family, the gear, or the toys.

Whether you’re conquering the highway in your MDX, carving canyons in the TLX, rediscovering adventure in the new Integra, or even contemplating the impossible with an NSX, there’s a box out there that fits your ride and your lifestyle.

Remember the golden rules: Know your roof type and weight limits. Measure twice! Prioritize fit and aerodynamics for your specific Acura.

Imagine the freedom: skis or snowboards ready for the slopes without cramping the cabin. Camping gear for the whole crew without a grunt fest packing the trunk. Luggage for that epic road trip where everyone actually has legroom. That’s the power of smart storage. Forget the limitations – your next adventure, big or small, just got a whole lot roomier.
