New 2026 Grand Design Foundation 42GD

The 2026 Grand Design Foundation 42GD is a brand-new luxury destination trailer platform introduced as part of Grand Design’s expansion into true residential-style park models. Designed for extended stays and seasonal living, the 42GD focuses on delivering a home-like experience with residential construction, spacious multi-room layouts, and modern high-end finishes. At roughly 44–45 feet in length with multiple slide-outs, it is built for those who want maximum space and comfort at a permanent campsite or long-term destination setup.

Inside, the 42GD emphasizes open-concept living with a true residential feel. The main living area is designed as a large great room layout, featuring wide opposing slides, oversized seating, and an entertainment center with fireplace. Large panoramic windows bring in natural light, enhancing the open, home-like atmosphere. The design prioritizes comfort for extended stays, with layouts that feel closer to a modern apartment or small home than a traditional RV.

The kitchen is fully residential in both layout and appliance selection. It includes a large center island, full-size residential refrigerator, convection microwave, oven, and extensive cabinetry storage, making it suitable for full-time cooking and daily use. The cabinetry, countertops, and finishes are elevated to match the destination trailer’s luxury positioning.

The private bedroom suite is designed for long-term comfort, typically featuring a king bed, large wardrobe system, washer/dryer prep, and residential storage solutions. The bathroom continues the residential theme with a large walk-in shower, porcelain-style fixtures, and expanded vanity space, supporting extended stays without compromise.

Built for seasonal and extended-use living, the Foundation 42GD includes high-capacity HVAC systems, upgraded insulation, heated underbelly protection, and enhanced electrical systems, ensuring comfort in a variety of climates. Exterior features include multiple slide-outs, power awnings, durable construction materials, and large storage compartments, reinforcing its role as a permanent-site destination trailer.
