The brand-new Grand Design Foundation 42GD was engineered from the frame up to be a true long-term destination home, not just a seasonal camper. As you walk up to this coach at Clear Creek RVs in Abilene, Texas, the first thing you notice is how solid and residential it feels. The front of the trailer features a painted and fiberglass-molded front cap with a massive 50 by 80 automotive-grade front window that floods the interior with natural light. Underneath, Grand Design uses a full aluminum framed structure with 101-inch-wide body construction and aluminum flooring on 12-to-16-inch centers for exceptional rigidity and long-term durability.
The Foundation 42GD sits on a heavy-duty chassis with a gross vehicle weight rating of 18,000 pounds and a dry hitch weight of 2,402 pounds, giving it the stability needed for full-time or extended stay use. Along the side, you have a full 20-foot power awning plus an additional 14-foot awning, creating an expansive outdoor living space for entertaining, relaxing, or simply enjoying your view. A rear elevated observation deck with composite exterior decking and integrated LED handrails gives you a true porch experience, something you normally only find on residential park models. Composite decking and waterproof woven vinyl flooring are rated at 2,500 pounds, so they are built to handle real foot traffic and furniture.
Grand Design also paid close attention to long-term ownership with a one-piece fiberglass roof, composite roof decking panels, and fully laminated fiberglass sidewalls. This system is designed to be low maintenance and highly resistant to leaks and weather over time. The slideouts are also roofed and sealed, eliminating exposed slide tops that often cause long-term problems. A full exterior convenience center, quad seal protection, brass plumbing fittings, and shutoff valves under every fixture further reinforce that this coach was designed for years of dependable use.
Let’s move inside the Foundation. The Grand Design Foundation 42GD feels more like a modern apartment than a trailer. The living area is anchored by a striking entertainment wall with a built-in electric fireplace, integrated storage, and a large TV area, all accented by contemporary design touches and adjustable lighting. Across from the entertainment center is a large residential sofa and seating area that opens directly into the kitchen, creating a wide-open floorplan that feels anything but narrow.
The kitchen is one of the highlights of this floorplan. A large center island provides generous counter space for meal prep and entertaining. Solid surface countertops, a residential GE dishwasher with sanitation cycle, a full GE kitchen suite with 18.6 cubic foot refrigerator, over the range microwave, four burner range, and an oven all come standard. The pull-out kitchen pantry with adjustable shelving, spice rack, and paper towel holder gives you true residential storage, while soft-close hardwood drawers, deep cabinet storage, and a built-in trash can keep everything organized and easy to access.
Moving toward the rear of the coach, you will find the bedroom suite designed for full-time comfort. The king-size bed sits in a private bedroom with generous closet space, washer and dryer prep, and plenty of cabinetry for long-term stays. The bedroom is separated from the living space, giving you a true home-like feel instead of a simple sleeping area.
The bathroom continues the residential theme with solid surface counters, a spacious shower, quality fixtures, and ample linen storage. Grand Design also includes heated and enclosed underbelly tanks, a 62K tankless water heater, and electronic tank heating pads so you can use this coach comfortably in a wide range of climates. The 42GD holds 83 gallons of fresh water, 106 gallons of gray, and 53 gallons of black, giving you excellent capacity for extended stays.
Above the master suite is a spacious loft space that makes an excellent space for guests or kiddos. The queen bed has its own TV and you will love all of the additional storage space found in this loft area.
What truly separates the Foundation from other destination trailers is how it is built. It uses a one piece 5/8 inch floor decking with a 25 year parts warranty, aluminum-framed walls and roof, automotive-grade front window, bonded square glass windows, and a full 3-stage water filtration system. Everything from the brass plumbing fittings to the self-leveling roof sealant is designed for long-term durability, not weekend camping.
This is a perfect coach for lake lots, hunting land, family ranches, long-term work assignments, Arizona roping camps, or for anyone who wants a true second home that they can take with them. Whether you are hosting family, enjoying the outdoors from the rear deck, or settling in for a season, the Foundation 42GD is built to deliver residential comfort in a mobile format.
Grand Design backs the Foundation with one of the strongest warranties in the RV industry, including a 3 year structural warranty and a 1 year base warranty, all transferable for added peace of mind.
