    Floorplan - 2014 Keystone RV Mountaineer 331RLT

    Step into this 331RLT Mountaineer fifth wheel by Montana and be pleasantly surprised by the spaciousness you see with three large slide-outs.

    Starting in the main living area that you walk into there are two slides opposite one another which provides an open concept home-like feel. The slide to your immediate left features a free standing dinette and sofa with overhead storage cabinet. Along the rear wall there is a hide-a-bed sofa and a complete overhead cabinet the width of the unit.

    The opposite slide features a desk and entertainment center with TV and optional fireplace below. There is also a refrigerator and three burner range in this slide-out. You will also find a separate counter area with more overhead cabinet space and a double kitchen sink for easy clean-up. In the center of the room you have a roll away kitchen island that is perfect for meal prep.

    Step up to a side aisle bath featuring a tub/shower, toilet and sink. There is a hallway closet too.

    In the front bedroom you will enjoy a comfortable nights sleep on the slide-out queen size bed with nightstands, front closet with sliding doors that has been prepped for a washer and dryer if you choose to add for convenience. There is also a dresser with HD TV above, a linen cabinet, and so much more!

    You might even like to choose an optional king size bed instead of the standard queen, electric fireplace, or optional theater seating in place of the sofa slide.

Manufacturer Logo

When Cole Davis founded Keystone RV in 1996 his vision was clear:  Build a quality RV loaded with features priced thousands less than other RVs on the market.  To accomplish his goal, Cole would recruit and build a strong team, focus on keeping overhead low, and empower the people closest to the customer to make decisions.

Within a few short months after opening the doors, Keystone produced its very first camper.  Delivering big on quality, features and value, the public fell in love with it.  A star was born!  As the appetite for the camper increased, new Keystone models were added to satisfy growing customer demand. Along with this tremendous growth came the need for expanded production.  To meet this need more manufacturing plants were built and staffed.

From new floor plan designs to patented inventions, Keystone leads the way in product innovation.  One reason is our mission to stay close to the customer.  When talking with campers or visiting dealerships, our sales, product development, and service teams, are always looking for ways to improve the camping experience.  And we don't stop there.

Every member of the Keystone family is encouraged to contribute to making our campers absolutely the best possible.  Through something we call Kamp Keystone, our employees camp free of charge at local campgrounds in the Keystone trailers we supply.  Each year hundreds of our production workers, administrative staff and service team enjoy a day (or a week) at Kamp Keystone.  Their evaluation of the experience and the feedback they provide results in continued product improvements.  Ask us if we use our RVs...the answer is YES!
