The 2026 Grand Design Influence 3503GK is a luxury rear kitchen fifth wheel designed for couples who want residential-style comfort, wide-open living space, and high-end construction in a towable full-profile RV. At approximately 38’3” in length with a dry weight around 13,800 lbs and a GVWR of 16,800 lbs, this model sits in the upper tier of the Influence lineup, offering a true “home-like” layout with expansive storage, triple slides, and premium finishes built for extended travel or seasonal living.
Inside, the 3503GK is built around a true rear kitchen design, giving you one of the most functional cooking and entertaining spaces in its class. The rear layout provides abundant countertop space, a full residential-style appliance package, and a large pantry that makes longer trips feel effortless. Moving forward, the main living area opens up with opposing slide-outs, theater seating, and a tri-fold sofa, creating a spacious lounge environment centered around an entertainment center and fireplace for a residential feel.
The kitchen is a standout feature, offering a 16 cu. ft. 12V residential refrigerator, three-burner cooktop, oven, microwave, and deep sink setup, all designed to support full-time or extended-stay cooking. Storage is a major strength, with a large pantry and cabinetry throughout the main slide that keeps everything organized even on longer trips.
At the front of the coach, the private master bedroom includes a walk-around queen bed (king optional), wardrobe storage, and washer/dryer prep, making it fully capable for extended stays. The adjacent bathroom is centrally located and features a large walk-in shower, porcelain toilet, and vanity with storage, giving it a true residential bathroom feel.
Built for long-term durability, the Influence line includes laminated fiberglass construction, a fully enclosed and heated underbelly, and upgraded insulation packages designed for extended-season camping. Exterior features typically include dual power awnings with LED lighting, a 6-point auto leveling system, pass-through storage, and a reinforced chassis with heavy-duty running gear, making setup and travel easier and more stable.
