Winnebago ARKA 20Z

Expedition-style box on a Ram 5500 4x4 diesel, and the one Winnebago motorhome here with a four-season rating, built around hydronic in-floor heat and heat-recovery ventilation. A full-height heated rear garage with L-track sits behind a convertible front bunk that makes a king, queen or twins, and the shower is hidden beside a cassette toilet. The 48V power system and a 15,000-lb hitch come on every truck, while the Overland trim adds 41-inch tires and roof solar. Around $332,000.
