The AT Overland Aterra XL Flatbed (XLF) Camper isn’t built for campgrounds or RV resorts. It’s an overland truck camper designed for off-grid adventures away from the crowds.
AT Overland’s philosophy has always been clear: build it light, build it strong, and make sure every system works in the real world. Since I first reported on the Aterra XLF back in 2021 and reviewed it in 2022, AT Overland has continued to refine the platform, pushing it into a new generation.
The latest version doubles down on durability, boosts power systems, and tightens up details across the board.
Even Stronger Shell
At the heart of the Aterra XLF is its shell. It’s built from fiber-reinforced thermoplastic honeycomb composite and coated in polyurea; it strikes a balance between lightweight efficiency and serious strength. While the exterior coating isn’t my favorite look, it is extremely durable. The shell structure and facing have also been doubled in thickness for even more durability and impact resistance.
The lightweight shell helps the camper achieve a dry weight just over 1,600 pounds. This means it’s well-suited for 3/4- and 1-ton trucks.
This camper is engineered for the abuse that rugged terrain and harsh weather inflict.
A Thoughtful Interior
Step inside, and the Aterra XLF feels more like a functional off-grid cabin than a tricked-out RV. With 6 feet, 7 inches of headroom and a king-size bed, it’s built for comfort while thoughtfully using all available space.
Five double-pane Arctic Tern windows and a secure entrance door keep the space bright and airy, while still sealing tight to ward off trail dust and extreme weather.
The galley is simple but high-quality: it has a flush-mount stainless stove and sink, Plyboo bamboo countertops, and a 90L National Luna fridge/freezer. It looks good, is extremely durable, and is the perfect equation for creating gourmet meals in the backcountry.
Systems That Matter
The Aterra XLF runs systems chosen for reliability, and are highly tested in the field over many years by AT Overland.
Heat and hot water come from Truma units, a proven choice for four-season use. A 30-gallon freshwater tank, Wrappon Trekker waterless toilet, and inside/outside showers extend self-sufficiency and comfort well beyond what most truck campers in this class can offer.
As with most modern overland campers, the Aterra XLF power systems have evolved in the past few years to provide impressive, extended off-grid electrified adventures. The system here comes with a 320Ah lithium battery bank, three times the capacity of earlier offerings. That is kept charged via shore power, 550 W of roof-mounted solar, and a Redarc 75A DC-DC charging system.
The system is also Starlink Mini–ready for those who need to stay connected everywhere they go.
Ventilation is handled by a 10-speed roof fan. An optional fresh air replenishment system can be added for improved air quality and reduced condensation in cold environments. For hotter climates, air conditioning is available and comes with an additional 320Ah battery to run it longer off-grid.
4-Season Life on the Road Less Traveled
What separates the Aterra XLF from many other overland truck campers is how well it’s designed for actual long-term use. Storage is ample and thoughtfully placed, and all critical systems are housed inside the insulated shell — protected from extreme temps and rugged environments.
Day-to-day life inside is smooth thanks to details like:
- USB-A and USB-C and 12V outlets
- Dimmable LED lighting
- Insect-screened ventilation
- A layout that transitions quickly between travel, cooking, and sleeping modes
It’s the type of camper you can actually live in for weeks — whether you’re ripping down desert two-tracks in Baja or parked high in the Rockies waiting out a winter storm.
Cost of Capability
The AT Overland Aterra XLF isn’t cheap — in construction, components, or price tag. Pricing for the camper starts at $82,000 — with fully optioned builds reaching $98,000. But buyers aren’t purchasing luxury trim or a short-term habitat; they’re investing in an engineered tool for extended, rugged travel.
When paired with an appropriate truck platform — like the AEV upfitted Ram 3500 shown here — it becomes a true four-season, round-the-world–capable expedition vehicle.
AT Overland Aterra XLF in the Wild
The Aterra XLF proves that AT Overland is still pushing the bar forward in the overland camper space. It’s not about flashy features or luxury glitz, it’s about creating a platform that works in the wild — day in and day out, year-round.
If you’re ready to leave the crowded campgrounds behind and actually live out of your rig for weeks — or longer — at a time, the AT Overland Aterra XLF is one of the most capable overland truck campers on the market. It’s a tool you can count on, as you’ll have what you need when you need it, no matter where the trail takes you.
