Loads of pickup campers we've looked at over the years pop upward to expand interior headroom, but far fewer pop out. The all-new Roam Rider SL does both, and it pops outward twice, sliding wings out of both sides to add an additional 20 cubic feet (566 L) of interior space. The sliding continues inside, where amenities slide open and closed rather than occupying finite space permanently. Roam Rider then manages to house a deconstructed part-time kitchen, deployable interior bathroom, L-shaped seating area/solo bed, and RV king-size master bed, all fit atop the 5.5-foot short bed of pickup trucks like the Ford F-150, Toyota Tundra and Chevy Silverado.
