Grand Design Recreational Vehicles is a superior quality manufacturer of towable fifth wheel and travel trailer RV's. Based in Middlebury, IN, Grand Design RV focuses on providing the highest quality and more premium standard features than any other RV's in their class.

Founded by close friends Don Clark and brothers Ron and Bill Fenech (each having over 25 years of experience in the RV industry).  Although they have lead some of the most successful companies in the RV industry, and are proud of their accomplishments at Keystone RV, they recognized that it was becoming more difficult to stay in touch with the needs of customers, employees, and the products being built. 

So, in 2011 they began pursuing their dream of reconnecting on a more personal level with customers and dealers.  The result of that pursuit is Grand Design RV.  A company designed to create recreational vehicles that provide more features, better designs and unparalleled customer support!
