The 2026 Grand Design Influence 3704BH is a high-capacity bunkhouse fifth wheel designed for larger families or groups who want residential living space, multiple sleeping zones, and premium construction in a full-profile luxury RV. At approximately 40’4” in length with a dry weight around 14,800 lbs and a GVWR of 16,800 lbs, this model delivers one of the most spacious and versatile layouts in the Influence lineup, making it ideal for extended travel, seasonal camping, or full-time RV living.

Inside, the 3704BH is built around a true residential-style floorplan with a dedicated bunkhouse, expansive main living area, and private master suite, giving everyone in the coach their own defined space. The bunkhouse is a standout feature, offering multiple sleeping areas for kids or guests along with storage and optional entertainment space. This separation from the main living area helps maintain privacy and comfort during longer stays.

The main living area features opposing slide-outs that dramatically open up the space, creating a wide, open-concept layout centered around theater seating, a sofa, and an entertainment center with a fireplace. Large panoramic windows bring in natural light, making the interior feel even larger and more residential.

The kitchen is centrally positioned and designed for serious travel cooking, including a residential 16 cu. ft. refrigerator, 3-burner cooktop, oven, microwave, and solid-surface countertops, along with a large pantry for extended trips. The layout is designed to support both everyday meals and larger family cooking needs without feeling cramped.

Up front, the private master bedroom includes a walk-around queen bed (king optional), wardrobe storage, and washer/dryer prep, giving owners a true full-season setup. The adjacent bathroom features a large walk-in shower, porcelain toilet, vanity, and storage, positioned for convenient access from both the bedroom and main living area.

Built on Grand Design’s heavy-duty Influence platform, the 3704BH includes laminated fiberglass construction, a fully enclosed and heated underbelly, and upgraded insulation packages designed for extended-season camping and colder climates. Exterior features typically include dual power awnings with LED lighting, 4 slide-outs for maximum interior expansion, pass-through storage, and a 6-point auto leveling system for easier setup and stability at camp.
