The 2026 Grand Design Imagine 3100RD is a premium rear living travel trailer designed for campers who want a residential-style lounge experience, dual-slide spaciousness, and extended-season capability in a towable RV. At approximately 35’11” in length with 2 slide-outs, it delivers one of the most open and home-like interiors in the Imagine lineup, making it especially popular with couples and small families who prioritize comfort and entertainment space.
Inside, the 3100RD is centered around a true rear entertainment lounge layout, featuring large panoramic windows that create an open, residential atmosphere. The rear living area typically includes opposing seating (sofas or theater seating depending on configuration), an entertainment center with a large LED TV, and a fireplace, making it feel more like a living room than a traditional RV. The dual slide-outs dramatically expand the interior, giving you wide walking space and a comfortable social layout.
The kitchen is centrally located and built for real-world camping use, offering a 3-burner cooktop, oven, microwave, and a 10 cu. ft. 12V refrigerator, along with ample counter space and storage cabinetry. A freestanding dinette adds residential flexibility for dining, working, or additional seating.
At the front of the unit, the private queen bedroom provides separation and privacy with wardrobe storage, overhead cabinets, and walk-around space. This layout makes longer trips significantly more comfortable, especially for extended stays where personal space matters.
The centrally located bathroom includes a walk-in shower (approximately 30” x 36”), vanity, and storage space, designed for convenience and accessibility from both the bedroom and living area.
Built with Grand Design’s focus on durability and extended-season use, the 3100RD features laminated aluminum-framed construction, a heated and enclosed underbelly, and upgraded insulation packages (including high R-value roof and floor systems). Exterior highlights include a power awning with LED lighting, pass-through storage, solar prep, and upgraded entry steps, making it well-suited for both campground camping and longer seasonal stays.
