The following is a report from GearJunkie.
AT Overland’s new Aterra ASI camper sets a fresh standard in versatility, blending ultra-lightweight construction with innovative modularity. Available both as a DIY-ready shell and a fully equipped model, this slide-in camper caters to every kind of adventurer — from passionate DIY builders to turnkey explorers seeking premium features straight from the factory.
AT Overland has earned a strong reputation by crafting rugged, functional, and innovative campers designed specifically for adventure travelers. The company’s latest release, the Aterra Slide-In (ASI), continues this legacy — delivering modular versatility, lightweight durability, and serious off-road capability in the competitive slide-in camper market.
As the newest member of AT Overland’s Aterra series, the ASI represents a significant evolution in slide-in camper design. It’s a fully enclosed, hard-sided slide-in unit built from advanced honeycomb composite materials. It’s ideal for truck campers who prioritize adaptability, ease of use, and durability in demanding off-road conditions.
Lightweight & Durable Construction
The ASI’s appeal begins with its innovative and lightweight construction. The camper utilizes an advanced honeycomb composite structure, reinforced by a polygonal geometry, and coated inside and out with UV-stable hybrid polyurea and polyurethane.
This 
construction technique provides outstanding durability against extreme weather and rugged terrain, while significantly reducing camper weight compared to traditional builds.
For those looking to build a rugged, hard-sided camper that’s paired with a mid-sized or half-ton full-size pick-up, the DIY-ready shell starts at an impressively low 757 pounds, making it extremely attractive for those with limited payload capacity. Even the more fully featured Standard model tips the scales at just 817 pounds, ensuring flexibility for extended, off-grid adventures.
I had the opportunity to take a look at a fully equipped ASI camper at AT Overland’s headquarters in Prescott, Ariz. It was mounted in a 6.5-foot-bed Toyota Tundra.
And, equipped with optional amenities such as a forced air heater, air conditioner, water system, shower, fridge/freezer, toilet, and storage compartments, it weighed in at a reasonable 1,157 pounds. Its aerodynamic design and rigid structural geometry ensure minimal strain on your truck, whether driving highways or tackling rough off-road trails.
