The Denali 1S delivers exceptional versatility in a streamlined single-slide design. Perfect for adventurers seeking the sweet spot between capability and maneuverability, this flatbed truck camper features a spacious rear dry bath and an oversized kitchen built for serious camp cooking. Smart storage solutions throughout maximize every inch, while the convenient side-entry layout ensures easy access whether you're parked in tight trailheads or wide-open landscapes.
Built one at a time in Emmett, Idaho, each Denali 1S undergoes rigorous quality testing. Our forward center of gravity design ensures optimal truck handling, while the flatbed mounting
system provides unmatched stability and accessibility.
One of the largest capacity water tanks in the industry means 2-3 weeks off-grid without refills. Includes 78-gallon grey and 36-gallon black tanks.
Return air conditioned basement maintains optimal temperature for tanks and equipment without forced air, improving efficiency and reliability.
The kitchen slide-out transforms the Denali 1S interior—delivering big-camper comfort in a rugged flatbed platform.
Strategic weight placement ahead of rear axle improves handling, reduces sway, and maximizes payload capacity.

Jesse and Anca have been wonderful to work with. They care deeply about their customer’s satisfaction. They are ready and willing to do all they can for you. When we picked it up with our horse trailer, Jesse made sure we had all we needed for our way back. Excellent product and excellent customer service!
Let me be honest. This rig is nicer than 90% of the houses and apartments I lived in until I got financially solvent a couple of decades ago. Come on, really? A truck camper? It even has a fireplace in the kitchen’s island. How unbelievably cool is that?
