Manu-Facts:

Grand Design Logo
In 2012, we started with a blank canvas to pursue that better way, a different way, than what had been done before. A company whose culture requires a long-term, personal connection with our customers, employees, and dealers – that company is Grand Design RV. Our business model of doing the right thing has led us to unparalleled years of growth.
 
Our local workforce has been hand-picked and has an excellent reputation for second-to-none industry craftsmanship, and our CEO and Senior Management actively work with the production facilities to help build the team and develop products.
 
At Grand Design we've raised the quality bar by putting every unit through a series of quality inspection gates during the manufacturing process. Once completed, the unit undergoes a comprehensive “final finish” inspection. Every one of our coaches is shipped to a PDI (Pre-Delivery Inspection) area where they are put through a rigorous 300+ point inspection checklist before being shipped to our dealers.  And, we back every one of our coaches with a 3-year limited structural warranty.  
 
At Grand Design our goal is simple – continue leading the industry with quality products while improving the customer’s RV experience before, during and after the sale. We strive for nothing less than customers for life and we would be honored to personally welcome you to the Grand Design RV family!
