This custom-built camper was specifically designed for full-time or long-term travel, making it well-appointed for those who value self-sufficiency and off-grid capability. It was built by a professional in Colorado (Mesa Overland), and the quality is second to none.

As a composite camper, it features zero-wood construction. Its lightweight for a 10′ flatbed camper (Mesa Overland “Sunkat”), wont rot, and has excellent insulating properties. It is fully equipped with all systems needed to stay self-contained in the backcountry, no propane or hookups required.

The camper is designed for year-round use and would make for an excellent home base for skiing and other winter activities. The floor has an R value of 12, while the walls and ceiling are R15. Additionally, the camper has two sources of heat: a diesel heater and electric radiant heat floors. All plumbing is contained in the heated areas, making it truly four-seasons capable.

The truck has a hitch and the rear L-track system on the camper is suitable for mounting boxes, etc., so there are plenty of ways to store your winter gear externally!

The build was completed at the end of May 2025. In that time, we have called it home, and it has only seen state parks and mild forest roads. Unfortunately, we have encountered some minor health concerns that would be much easier to address from a home base. This is our reason for selling.

Current lead times on a build like this are months (if not longer), so if youve had your heart set on a rig like this and want to enjoy life on the road sooner rather than later, this is the camper for you!

Feel free to ask any questions, and Ill do my best to answer them promptly.

Current Location: Missoula, Montana. We are willing to be flexible with travel arrangements (within reason).

Price: $185,000 for the entire rig. We may be willing to separate the camper and truck for the right deal.
