Many retirees are finding that life can be restrictive in a home designed for full time living. Grand Design RV offers a complete line of Extended Stay vehicles designed to remedy this issue. Numerous camping resorts in the USA and Canada now offer versatile Extended Stay plans. Because of this, many Grand Design RV owners are enjoying our products as a part-time “second home”. They find it considerably more affordable than a condo or small house and much more versatile because they can park it in superb locations and move it whenever they please.

All our Fifth Wheels and Travel Trailers are “Extended Stay Approved”. This means that we have engineered them with many of the residential-style qualities found in a fine home. To this end, we have created spacious open living areas and appointed them with extra large windows, large refrigerators, walk in closets, large queen/king beds and many other home-like amenities.     These features help translate your extended stay experience into full-time enjoyment!
