USED 2015 Keystone MONTANA 356TBF

The 2015 Keystone Montana Mountaineer 356TBF is a five-slide fifth wheel that was built for families who genuinely need the space, and it delivers on that promise in every direction. At nearly 40 feet, the floor plan offers a full living and kitchen area up front with opposing slides that open everything up, a raised front master bedroom with a queen or optional king bed and full bathroom, and then the real showstopper for families: a rear bunkhouse with dual slides that give the kids a space that feels like their own room. One bunkhouse slide features a hide-a-bed sofa with a fold-down bunk above, while the other holds a wardrobe with TV and another bunk above, all served by a conveniently located half bath with its own private entrance. Sleeping up to ten people, this is a fifth wheel that handles the whole crew without anyone feeling like they drew the short straw.

Gently used and well cared for, this Mountaineer has held up well through what the 356TBF was designed for: real family camping. A 35,000 BTU furnace, 15,000 BTU air conditioner, two full bathrooms, a 66-gallon fresh water tank, and washer and dryer prep speak to just how complete this unit is for extended stays. On a pre-owned unit of this size and age, a thorough walk-through of all five slideouts, the hydraulic leveling system, and both bathrooms is always a smart step, but for a family ready to step into a serious fifth wheel at a used price, the 356TBF offers a lot of trailer for the money.
