Why the 12SE?

The 12SE Slide-In Camper offers four-season performance, premium finishes, and a spacious slide-out design—all in a rugged, go-anywhere package. With a queen bed, dry bath, and full kitchen, it’s built for comfort without compromise.

system provides unmatched stability and accessibility.

Customer Review

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?
