The 2026 Grand Design Influence 3003RL is a premium rear living fifth wheel designed for couples who want residential comfort, high-end construction, and extended-season capability in a mid-profile luxury coach. At approximately 34’11” in length with a dry weight around 12,500 lbs and a GVWR of 18,000 lbs, it delivers a strong balance of towability and upscale livability, making it one of the most popular floorplans in the Influence lineup for long trips and full-season camping.
Inside, the 3003RL features a true rear-living layout with opposing seating and entertainment space, designed to feel more like a residential apartment than a traditional RV. Large panoramic windows surround the living area, bringing in natural light and giving the rear lounge a wide-open feel. The main slide-out expands the living room significantly, typically housing theater seating and/or a tri-fold sofa across from a full entertainment center with fireplace.
The kitchen is centrally located and built for real travel cooking, featuring a 3-burner cooktop, oven, microwave, 16 cu. ft. residential-style refrigerator, and solid-surface countertops. A large pantry and smart storage design make it easy to stock up for longer stays without feeling cramped.
Toward the front, the private master bedroom includes a residential queen bed (king optional), wardrobe storage, and washer/dryer prep, offering true full-time RV potential. The adjacent bathroom is well-sized for a fifth wheel in this class, with a walk-in shower, porcelain toilet, vanity, and linen storage, making daily use comfortable and practical.
Built on Grand Design’s reputation for durability, the Influence line includes laminated fiberglass sidewalls, a fully enclosed and heated underbelly, and upgraded insulation packages for extended-season camping. Exterior features typically include dual awnings with LED lighting, pass-through storage, a roof ladder, and a 6-point leveling system, making setup and campsite living simple and stable.
