This Sprinter fifth wheel is yours for the taking!

After you whip up dinner and a fabulous dessert, you can enjoy them at the wall-mounted dinette with four chairs. The separate living room has a residential feel with its fireplace, 50" LED HDTV, two queen-size tri-fold sofas, and full-reclining theater seating with massage, lights, and USB. If you find yourself tired out from the day's travels, you can head straight to the rear private bedroom to fall asleep on the 70" x 80" king-size bed after taking a hot shower in the residential shower and change into some comfortable pijamas from the wadrobe and dresser in the bedroom.

The heated pass-through storage includes lockable slam latch baggage doors so you can easily pack your gear, and the one-touch 4-point leveling system features return hookup memory to have you set up in no-time. Head inside to find DynaSpan Marine Grade floor decking, Thomas Payne luxury collection furniture and residential style seamless marbled countertops to name a few comforts. The Sprinter also includes a Suburban tankless on-demand water heater, black out aluminum wheels, plus a 30k BTU furnace to ensure your comfort!
