Excellent condition AT Overland Aterra ASI Slide-In Camper. Aterra Slide-in for 6.5' Full Size Trucks. Purchased March 14th 2026. One single season of camping.

The Aterra Slide-In Camper is a fully enclosed composite expedition camper engineered for travelers who want the comfort and security of a hard-sided camper without the weight, bulk, or limitations of traditional RV-based designs.

Built using AT Overlands lightweight honeycomb composite construction, the Aterra Slide-In delivers exceptional durability, modular flexibility, and true off-road capability in a platform designed to evolve with your adventures.

This trailer bolts directly to your truck's bed. No strapping this trailer in like the competition. It is fully off-road capable.
