The 31SS runs on serious hardware, a Cummins 6.7L turbo diesel backed by an Allison six-speed and air brakes with ABS, all on a Freightliner M2 chassis with 15,000-lb tow capacity. Inside, it fits a King bed and a cab-over bunk without feeling stretched, and the outdoor entertainment setup means you're not stuck inside at camp. The all-aluminum, composite fiberglass construction skips exterior wood entirely, and dual-pane frameless windows with integrated day/night shades give it a cleaner, more residential feel than most Class Cs at this length. The optional Xplorer Package, with 540Ah of lithium, 1,000W solar, and an insulated utility bay. Makes a compelling case for going seriously off-grid.
