2021 Keystone RV Carbon 338

The 2021 Keystone Carbon 338 is a robust and well-equipped tandem-axle fifth-wheel toy hauler designed for the adventurous family or weekend warrior. Stretching nearly 36 feet long and standing over 13 feet tall, it boasts a 10-foot separate garage in the rear—perfect for hauling ATVs, bikes, or motorcycles—with certified 5,000 lb tie-downs and durable rubber flooring. Inside, two power slide-outs expand the living area and master suite, offering space for a 97-inch reclining sofa, U-shaped kitchen with solid-surface counters and a sizeable 12-cu-ft stainless steel fridge, plus a single dinette table.

Sleeping accommodations include a queen-bed master bedroom, a lofted twin bed above the garage, and a convertible electric bed with opposing sofas—allowing up to seven people to sleep comfortably. Thoughtful living features like a 50 LED TV with surround sound and in-floor heating ducts ensure comfort and convenience. The full bathroom features a standard shower and porcelain toilet, while camper amenities include washer/dryer prep, Onan 5,500 W generator, and a 19-foot LED-lit electric awning.

With a dry weight of about 12,100 lb, 4,700lb cargo capacity, a 94-gal freshwater tank, and 50-amp service, it’s self-sufficient and ready for long trips off the grid. Altogether, the Carbon 338 blends adventure-ready hauling capability with residential comforts in a rugged, well-appointed package.
