The Overland Explorer Alpine is a lightweight rear entry composite pop up camper designed specifically for full size 1/2 or 3/4 ton trucks with an Alumatray flatbed bed or similar. These campers are designed and built using OEV’s proprietary composite panel and aluminum extrusion system. The result is extremely light weight, extremely tough, and extremely warm (or cool!) camper. The extrusions are designed specifically for this application, thermal transfer has been almost eliminated keeping the interior more comfortable in inclement weather than competing aluminum framed campers.
