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!
