New Aterra XL Flatbed Camper to Debut at 2021 Overland Expo West

AT Overland will be debuting the new Aterra XL flatbed camper at the 2021 Overland Expo West in Flagstaff, Arizona, 24-26 September 2021.

Engineered by David Soza of Tern Overland and collaboratively built with AT Overland Equipment, the full-size, flatbed camper features an innovative, lightweight fiber reinforced thermoplastic honeycomb composite construction as well as Tern Overland’s popular acrylic windows and hatches and doors.

“Our specialty is engineering and design, so when we went looking for a manufacturing partner, AT Overland was at the top of our list,” explained David Soza, CEO of Tern Overland. “AT Overland has a long history of excellence in manufacturing, innovation, customer support, and marketing. Through our partnership, AT Overland will be assembling, outfitting, and exclusively marketing the Aterra.”

With a dry weight of only 1,100 pounds dry, the AT Overland Aterra XL was designed specifically for full-size trucks with the requisite payload rating including, half-ton, 3/4-ton, and one-ton pickup and cab chassis trucks with 6.5-foot and 8-foot or longer flatbed trays. With a floorlength of 6-feet 5-inches, the Aterra will universally fit any 80×80-inch tray, including those made by SherpTek, FiftyTen, Ute, Norweld, and Alumalite.

Featuring a modern, geometrical design in an attractive, stone grey color, the Aterra XL features a structure that is both strong and lightweight and able to withstand the rigors of the worst roads on the planet. The flatbed camper features a side-door on the passenger side with a rear dinette, a driver side kitchenette, and a 78×60-inch queen-size mattress cushioned with the excellent Froli Travel Modular Sleep System.

Designed and built for sustained four-season travel, standard features include five Arctic Tern double-pane acrylic windows, a Truma Vario furnace and a Truma AquaGo on-demand water heater, and Dometic two-burner sink/stove combo with glass top, a MaxxAir Dome Fan, and a National Luna 90L dual-zone refrigerator-freezer. The camper also features an indoor shower integrated in the rear dinette.

Additional standards in this full-size flatbed camper include a 20-pound propane tank, a 30 gallon fresh water holding tank, a Wrappon waterless toilet, inside and outside showers, a 105 amp hour lithium battery, a 400 watt solar power system, and a National Luna NLDC 40 amp DC to DC charging system with an integrated MPPT solar charge controller.

The Aterra XL features a comfortable living space with convenient and practical storage solutions. These include 10 Step 22 Stingray Cabinet Storage Cubes, two Step 22 Stingray Cabinet Storage Half Cubes, three under-bed storage drawers, three hidden under-bed compartments, a wardrobe closet measuring 10 x 19 x 35 inches, and dinette seat storage. The interior height is a full 6-feet 3 inches with a cabover height of 42 inches.

This modern, cutting-edge camper is also equipped with the sPOD BantamX Power Distribution System with Bluetooth. This eight-circuit (expandable) digital controller integrates control of all lighting and appliances through CAT-5 Ethernet. The BantamX is controlled with a touchscreen controller, but a Bluetooth app allows the owner to control everything outside of the camper as well. But the Bantam-X does more than just provide power to lights and appliances, it also provides protection against over current, over heating, shorts, low voltage, and reverse polarity protection for the camper’s DC system.

For those looking for extended time off-grid, AT Overland will be offering numerous options to trick out this camper even more. These options include additional lithium batteries for a total of 315 amp hours, additional solar panels for a whopping 800 watts total, an exterior awning, mechanical camper jacks, a rear accessory mounting rack suitable for fuel/water cans and recovery boards, a “fresh air replenishment system with condensation removal,” and a paint match to the vehicle.

A mid-size Aterra model will be introduced later, possibly in 2023. As a matter of fact, the Aterra prototype was tested on a 2019 Toyota Tacoma. The 600-pound prototype took over two years to design, build and test.

“The Aterra XL is going to be the one of the lightest weight, fully-equipped campers that you can buy, period,” explained Mario Donovan, co-founder and CEO of AT Overland. “We’re going to be right at 1,100 pounds. Nobody can touch that. Another notable thing is that there are no thermal bridges on this. From a BTU consumption standpoint, this camper is very, very efficient. When you look at pop-up campers, that tent is a thermal bridge, the aluminum framing found in today’s campers are thermal bridges. This camper has none. We will be releasing thermal images of the Aterra camper to show everyone just how tight it is. All of the windows are double-paned, there’s five windows, there’s the Tern Overland roof hatch and there’s also the window in the door, so that’s pretty significant in terms of light and the how air that can be moved without having to use a noisy fan. Each one of the windows is also equipped a thermal privacy shade and bug screen.  There is over 61,000 cubic inches of efficient storage spread among 24 individual compartments, addressing the age old camper problem of where to store your camping gear. In short, we are super excited to introduce the Aterra at the show.”

The official reveal of the AT Overland Aterra XL will take place at the 2021 Overland Expo West in Flagstaff, Arizona, 24-26 September 2021. The camper will be on display at the AT Overland booth (Q35).
