Description

The New 2026 Grand Design Solitude 390RK is a luxury fifth wheel built for buyers who want true residential comfort, upscale design, and a spacious rear kitchen layout. At 42 feet 5 inches with five slide-outs and sleeping for up to 6, this floorplan delivers the kind of open living space that makes extended stays and full-time-style travel feel more like home. Grand Design lists the 390RK with a 2,794-pound hitch weight, 15,000-pound UVW, and 19,000-pound GVWR, giving it the size, presence, and capability expected in a premium fifth wheel.

One of the biggest highlights of the 390RK is its raised rear kitchen, which creates a distinctive layout and gives the main living area a refined, residential flow. Dealer listings also highlight sought-after features like dual-sink bath vanity, bar top with chairs, and an exterior sliding tray, all of which add convenience and livability for longer trips. This is an especially appealing floorplan for couples who want a luxury fifth wheel with generous entertaining space and a more upscale everyday feel.

The 2026 Solitude line is also built with premium features buyers expect in a high-end towable. Published feature lists include high-gloss gel coat exterior sidewalls, frameless tinted windows, power patio awning with integrated LED lighting, slam-latch baggage doors, and a well-appointed bedroom with a 60" x 80" queen bed, under-bed storage, nightstands with USB ports, and dresser storage.

For travel flexibility, the 390RK offers strong utility specs with 81 gallons of fresh water, 106 gallons of gray water capacity, 53 gallons of black water capacity, and 50-amp service, helping support longer stays and a more comfortable camping experience. For shoppers looking for a luxury fifth wheel with a unique rear kitchen design, residential touches, and the upscale reputation of the Solitude line, the New 2026 Grand Design Solitude 390RK is an excellent choice.
