A new take on the overland truck camper is coming. The AT Overland Aterra flatbed truck camper is a no-nonsense, full-featured, go-anywhere overland home.
For years now, I’ve had campfire discussions about this new camper design with AT Overland’s owner/designer Mario Donovan. Ever since I designed and helped build my own custom truck camper, the EEXP, which I lived out of for many years, I’ve dreamed about camper design.
I’m acutely aware of the many design and construction deficiencies common among today’s truck campers. And so is Donovan, who has dealt with these deficiencies for over 20 years now. The Aterra marks his latest camper solution.
While rugged off-road trailers launched AT Overland into the limelight, the brand now stakes its name on a full line of pop-top truck topper campers. And though the Aterra camper isn’t a pop-top, it’s likely to achieve similar market success.

AT Overland Aterra XL
Donovan is always on the hunt for a better way to do things. So it’s no surprise he stands as one of the overland industry founders here in North America.
His latest concept, the AT Overland Aterra XL, is a hard-sided flatbed truck camper he designed for weekend warriors and multi-continent overlanders alike. The name comes from a combination of the company name “AT Overland” and the Latin word for earth, “terra.”
The Aterra XL looks perfect for two adults and a pet on long-term overlanding excursions. And it can work for up to three adults for shorter adventures. Donovan designed it to fit on any full-size pickup that can be outfitted with an 80 x 80-inch flatbed (most half- to one-ton trucks on the market today).
Why choose this over other campers? Because of its durability, light weight, and impressive use of space, which offers tons of storage and all the comforts of home.
Durable & Lightweight
Tern Overland took more than 2 years to engineer the unique shell construction that AT Overland will debut on the Aterra XL camper. The brand claims it’s the “world’s first fiber-reinforced thermoplastic honeycomb composite shell.”
That means the panels that constitute the shell of the camper are made of a fiberglass-reinforced plastic honeycomb with fiberglass skin on each side. The panels are then bonded together and the entire camper, inside and out (minus the inside of the roof) is PU-coated (in Stone Gray color).
The interior roof also gets additional insulation and a carpeted headliner, both for noise deadening and optimal indoor climate control.
This super-strong, lightweight shell construction creates a camper that can handle the abuses of long-term adventures across extremely rough terrain. So it is a true four-season camper and only weighs 1,100 pounds fully outfitted.
Inside, you have just over 6 feet 3 inches of headroom. The interior cabinetry attaches without any fasteners, which keeps any holes out of the shell. To attach the cabinetry and systems, aluminum extrusions are bonded to the interior of the shell. For the countertops and table, the Aterra XL sports Plyboo, an excellent material for strength, weight, and durability. It’s also sustainable and looks fresh and modern.
