GMC Acadia vs Honda Pilot for Car Camping: Cargo Space, Clever Storage & the Honest Pick

The GMC Acadia and Honda Pilot are both midsize three-row SUVs that fold flat into a workable bed, and they represent two different philosophies. The 2024 Acadia redesign made it one of the roomiest in the class at 98 cubic feet; the Pilot answers with 87 cubic feet but Honda's signature clever packaging — a removable seat and under-floor storage. Space versus flexibility is the whole story.

The short version: buy the Acadia for the bigger raw sleeping floor (98 vs 87 cubic feet); buy the Pilot for its removable second-row middle seat, under-floor storage, and TrailSport ruggedness. Both need the front seats slid forward for a six-footer, and neither runs climate all night.

Neither is a purpose-built camper, so the comparison is about which family three-row you'd rather sleep in occasionally. The Acadia gives you more room to stretch out and store; the Pilot gives you smarter ways to organize the room it has. Both fold their rear rows into a load floor that, with a thick pad, becomes a genuine one-or-two-person bed.

What follows: the cargo numbers, how each one sleeps, the flat-floor reality, power and weather for an overnight, and a clear buy recommendation — grounded in published specs rather than a single drive.

Cargo volume is sleeping volume, so start with the published figures:

• GMC Acadia (2024 redesign): 23 cu ft behind row three, 57 cu ft behind row two, 98 cu ft with both rear rows folded.
• Honda Pilot: 18.6 cu ft behind row three, 48.5 cu ft with row three folded, 87 cu ft with both rear rows folded.
• The gap: the Acadia leads at every configuration — about 11 cu ft more at maximum and several more behind each row.

For sleeping, the maximum figure matters most, and the Acadia's 98 cubic feet gives a longer, wider floor that fits two pads with more room for gear; the Pilot's 87 is still genuinely usable for one adult stretched out or two close together. Behind the third row, the Acadia's 23 cubic feet is the handier for a loaded family trip.

Neither floor is perfectly flat with the seats down, so a thick pad is essential to bridge the seams. Our guide on how to choose a car camping mattress size helps you match a pad to each SUV's usable rectangle, and a shaped car air mattress for SUV camping fits the folded floor better than a plain slab in both.

The redesigned Acadia is the pick when raw room leads. Its 98 cubic feet is among the most generous in the midsize class, and that translates to camping comfort: a longer floor for a taller sleeper, enough width for two adults on pads, and space to keep bins and a cooler off the bed. It sleeps like a bigger vehicle than its footprint suggests.

The extra volume helps daily trips too. With 23 cubic feet behind the third row, you can carry a family's gear without folding the cabin, then drop the rows only for sleeping. The tall, boxy cargo area gives headroom to sit up and change, and available 110-volt and 12-volt outlets keep a fan and devices running through the night.

The honest caveats are class-standard: a six-footer still slides the front seats forward for full flat length, the folded floor needs a thick pad, and the engine can't run climate overnight. What the Acadia lacks is the Pilot's removable-seat and under-floor storage tricks — it gives you more room, but fewer clever ways to organize it.

In practice, that extra volume changes how a night feels. With the longer, wider floor you can set up a full-length bed and still leave a corner for a duffel and a cooler, so nothing has to migrate to the front seats. Taller campers especially notice the margin — a few extra inches of floor is the difference between lying straight and sleeping curled. The Acadia simply hands you space to work with, and lets you decide how to use it, which many campers prefer to a fixed set of clever compartments.

The Pilot's camping edge is Honda's packaging cleverness. Its second-row middle seat is removable and stows under the cargo floor, and there is additional under-floor storage — so you can hide valuables, a recovery kit, or wet gear below the sleeping surface and keep the bed clear. For campers, that flexible, out-of-sight storage is genuinely useful and helps offset the Acadia's raw-space advantage.

The available TrailSport trim adds rugged hardware and a more capable attitude for dirt-road and light-trail access to campsites, and the 87-cubic-foot floor sleeps a solo camper comfortably or a couple snugly once padded and leveled. Available outlets cover a fan, lights, and charging, and the under-floor bin is a tidy home for a portable power station.

The honest caveats match the Acadia's: front seats forward for a tall sleeper, a thick pad to level the floor, and no overnight engine climate. The Pilot gives up about 11 cubic feet of maximum room to the Acadia, but its storage flexibility means the space it has is easier to organize into a clean camp setup.

For a lot of campers, that organization is the deciding factor. A tidy camp — gear stowed below the floor, valuables locked out of sight, the bed kept clear — is calmer and safer than a cabin crammed with loose bins, and the Pilot makes that easy without any aftermarket parts. The Acadia gives you more raw room to impose your own order on; the Pilot hands you order out of the box. Which you prefer says more about how you like to travel than about which SUV is objectively better.

Both SUVs build the bed by folding the third row, then the second, into a load floor, and both share the same honest limitation: it is not a perfectly flat, gap-free platform. Seams, a slight step, and seatbacks that don't sit dead-level with the cargo floor are normal for the class, not flaws unique to either vehicle.

The Pilot's removable middle seat and under-floor bins help you clear and organize the space before laying a pad, a small practical edge. Sleeping length is the same story in both: a six-foot adult usually slides the front seats forward to lie fully flat, and the Acadia's longer floor gives a bit more margin for tall campers. Sleeping slightly diagonally buys a few extra inches in either.

The fix is identical: a thick, insulated pad to bridge seams and add loft, plus attention to leveling the vehicle. If your site isn't flat, the method in our guide on how to level your car for sleeping with ramps or blocks keeps you from sliding overnight — worthwhile in any midsize three-row, Acadia or Pilot alike.

Neither SUV is a hardcore off-roader, but both reach the dirt and gravel roads that lead to most dispersed campsites. The Honda Pilot TrailSport adds all-terrain tires, extra ground clearance, and steel skid plates aimed squarely at that duty, while the GMC Acadia offers available all-wheel drive and an AT4 trim with a slightly more rugged setup and all-terrain attitude. Either handles washboard, shallow ruts, and muddy access roads with confidence.

Towing and clearance are comparable and useful: both pull enough for a small utility trailer or teardrop camper while still sleeping inside at the destination, and both have the ground clearance for maintained forest roads. The Pilot's TrailSport widens the margin on looser surfaces with its tires and skid protection; the Acadia's AT4 does similar duty while keeping the roomier cargo hold that defines it.

Fuel economy for both lands in the low-to-mid-20s mpg range depending on drivetrain, so neither is a hardship on a long trip to the trailhead. The honest limit is identical: leave the technical rock and deep sand to a body-on-frame rig, and stick to the graded dirt and gravel these family SUVs do well. Within that envelope, the real decision stays where it began — the Acadia's extra room against the Pilot's cleverer, more flexible packaging — rather than any gap in where they can physically travel.

Both SUVs are honest about the limit every gas vehicle shares: neither should idle to run heat or AC all night because of fuel waste, noise, and carbon-monoxide risk. This is the one area where an electric SUV clearly wins — but between the Acadia and Pilot, behavior is identical.

For keeping gear alive, both offer 12-volt sources and available 110-volt outlets, enough for a fan, lights, and charging. For a 12-volt fridge or heavier loads, a portable power station for car camping is the right tool in either — and the Pilot's under-floor storage gives that battery a tidy, out-of-sight home the Acadia can't quite match.

Climate comfort comes from your setup, not the engine. Reflective window shades cut heat and cold, a battery fan moves air, and good bedding does the rest. Because both cabins are similarly sized and well-sealed, the same tactics work in each — the vehicle is the shelter, your gear is the climate system.

Sleeping inside a sealed cabin brings the familiar moisture issue: two people breathing overnight fog the glass and dampen bedding by morning. The fix is the same in both — crack a window an inch or two, run a small vent fan, and never cook inside. The habits in our guide on how to reduce condensation when sleeping in a car apply directly to both SUVs.

For summer heat, both midsize cabins warm in the sun, so shade and airflow matter. Reflective shades, parking in shade, and a battery fan are the core moves, and the techniques for staying cool sleeping in a car carry over unchanged. The Acadia's slightly larger cargo volume gives marginally more air, but the difference is small.

For cold nights, the answer in both is your sleep system: a season-rated bag, an insulated pad with real R-value, and a 12V heated blanket for car camping. A midsize SUV cabin holds a little residual warmth, but you sleep as warm as your bedding allows — so invest there first, in the Acadia or the Pilot alike.

Keep these attributed figures handy as you plan a bed and a power setup:

• Acadia cargo: 23 / 57 / 98 cu ft — the roomier floor at every configuration.
• Pilot cargo: 18.6 / 48.5 / 87 cu ft — about 11 cu ft less at maximum.
• Pilot extras: removable second-row middle seat + under-floor storage; TrailSport trim.
• Sleeping fit: both need the front seats slid forward for a six-footer; the Acadia's longer floor gives more margin.
• Power: 12V plus available 110V; add a power station for a fridge.
• Climate: neither runs overnight — manage with shades, a fan, and bedding.

The trade is clear: the Acadia's 98 cubic feet of raw room against the Pilot's cleverer storage. If you want the most space to sleep and store, the Acadia leads; if flexible organization matters more, the Pilot's packaging closes much of the gap.

Both SUVs camp well once you avoid the errors common to sleeping in any three-row. These five cause the most rough nights:

• A thin pad on the folded floor. You'll feel every seam — use a thick, insulated pad to level the surface and add warmth.
• Not sliding the front seats forward. Tall sleepers need that length; set it up before dark.
• Wasting the Pilot's storage. If you own one, use the removable seat and under-floor bins to keep gear off the bed.
• Parking on a slope. Level with blocks or find flat ground so you're not sliding all night.
• Sealing the cabin tight. Crack a window so breath moisture escapes and the glass stays clear.

None of these depend on the badge. An Acadia or a Pilot with a thick pad, the seats set right, level ground, and a cracked window both deliver a comfortable night — leaving the real decision at raw room versus clever packaging.

Buy the Acadia if raw sleeping room and everyday cargo lead your list. Its 98 cubic feet make it the roomier camper — more floor for two adults, more space to keep gear off the bed, and a taller cargo area to move around in. For families and couples who want the most usable interior, the redesigned Acadia is the straightforward pick.

Buy the Pilot if flexible storage and practicality matter more than the last few cubic feet. The removable second-row middle seat, the under-floor bins, and the TrailSport trim make it the easier SUV to organize for camping and to take down a rougher access road. Its 87 cubic feet still sleep one adult comfortably or two snugly.

Either way, equip the same kit — a thick pad, shades, a fan, and a power station for a fridge — because that gear, not the badge, determines how well you actually sleep. Choose room (Acadia) or packaging (Pilot) based on how you organize and how many you carry.

The Acadia and the Pilot solve the same job two ways. The 2024 Acadia redesign gives it the roomier floor — 98 cubic feet against the Pilot's 87 — so it wins on raw sleeping and storage space. The Pilot counters with Honda's clever removable seat and under-floor storage, plus a rugged TrailSport, making the space it has easier to organize.

Pick the Acadia for maximum room; pick the Pilot for flexible packaging and practicality. Then equip either the same way — a thick pad, shades, a fan, and a power station — and manage climate with your gear rather than the engine. Do that, and either midsize three-row delivers a genuinely comfortable night out.
