The Thor Motor Coach Tellaro 20L is built around a clever use of vertical space: the retractable rooftop Sky Bunk adds a sleeping area overhead while the main cabin keeps dual Twin beds that zip together into a King with a memory foam cushion. A full enclosed wet bath sits at the rear, and the Ram ProMaster 3500 XT chassis makes the whole thing genuinely easy to drive, with leatherette captain's chairs that swivel, a leather-wrapped tilt/telescoping steering wheel, and a suite of active safety assists including blind spot, lane keeping, and traffic sign recognition. Off-road tires and black rims hint at the adventure-oriented kit: a Thule power patio awning with integrated LED lighting, a Thule roof rack and load bars, and a Thule bike mount on the rear door. The Sky Bunk configuration pairs a 190-watt flex solar panel with two 100Ah lithium batteries and a 1,000-watt inverter, so the Tellaro 20L can run well away from hookups.
