Retractable 50" LED Smart TV

If you're traveling and camping with friends and family, this coach is sure to come in handy with its triple slides and a bath and a half! Once you arrive at the campsite, set up the 20' power lateral arm awning with LED lights, unpack your gear from the pass-through storage, and watch the game with the exterior 40" LED TV. If you'd rather enjoy some time inside, you'll find the 68" theater seating across from the 50" TV to be accommodating, plus there is a 68" sofa and a 72" Dream Dinette for more seating space! This Riviera kitchen includes a pull-out countertop for more prep space, a two burner electric induction cooktop, plus a pantry and a 15.7 cu. ft. French Door residential refrigerator for food storage! When you're ready to turn in for the night you'll enjoy the Tilt-A-View inclining king bed across from a 32" LED Smart TV, and the full rear bath with ample space to get ready for bed!

With any Riviera Class A diesel motorhome by Thor Motor Coach, you will enjoy a luxury home on wheels wherever you decide to roam! You will appreciate a capable Freightliner CS-S straight rail chassis with an Atlas foundation and better fuel mileage with the Cummins ISB-XT 6.7L diesel engine. There is a spacious basement pass-through storage for your camp gear, a powered patio awning with LED lighting, and an exterior 40" LED TV for outdoor movie nights. You will be able to enjoy your coach for years to come thanks to the durable construction materials that include a welded tubular steel floor, Vacu-Bond laminated roof, walls, and floor, plus a one-piece domed roof membrane. The elegant interior is designed with luxury vinyl tile flooring, "Wyndham" cabinetry with “Rake” style cabinet doors & nickel finish hardware. Some of the amenities you'll appreciate on each model include the RapidCamp+ multiplex wiring control system, a tankless water heater, and an Onan RV QD 6000 diesel generator.
