Tennessee-based EcoTrek claims that many off-road campers on the market are little more than off-road tires mounted on teardrop and pop-up designs built for the road. By contrast, EcoTrek builds the 510 for off-road use from the ground up, starting with a MIG welded tubular 6063-T6 aluminum frame supported at critical areas with cross braces and gussets. That skeleton is skinned, inside and out, with an aluminum-polyethylene composite material that EcoTrek says is 3.5 times lighter than steel and 1.5 times lighter than standard aluminum. The interior is insulated, and the alu-composite panels are sealed together with butyl tape.
Each EcoTrek 510 is built to the customer's specifications and starts at US$11,995. Options include a $1,000 wrap in buyer's choice of camo, a $1,000 roof air conditioner, and a $300 AGM battery that EcoTrek recommends for serious off-roaders.
