Keystone Sprinter fifth wheel 3840LRK highlights:

There is much to love about this fifth wheel! Starting with the front full bathroom which has a dual sink vanity for two to get ready at once and heading to the rear kitchen where you will have everything you need to prepare the best home cooked meals. There are also two bar stools at the bar top so guests can socialize with the cook. If you need to get a little work done while you're away, then you can easily get it done at the desk with chair next to the reclining theater seating and the 16 cu. ft. refrigerator for quick access to a snack break. The private bedroom has a king bed slide to lay your head on at night, and if you need an extra sleeping space then you can utilize the sofa slide too. Inside the half bathroom is a countertop with an area prepped for a washer and dryer to be added so you can enjoy clean clothes throughout your entire trip!

 

The Sprinter fifth wheels by Keystone feature spacious living areas, plenty of storage, and outstanding towability. Each unit is constructed with 2" thick double welded aluminum frame construction, a fully walkable roof and slide out roof, and dual layer insulation to help extend your camping season. 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!
