At home, anywhere - If you're looking for more room, Solitude is the most spacious Extended Stay Fifth Wheel ever built. Taller ceilings, bigger cabinets, and a sweeping scenic window all make the Solitude a dream that you wake up to as long as you like.

EXCLUSIVE 101” Wide Drop-Frame SuperChassis - A full 5” wider than many coaches in its class, the widebody chassis allows for more livable floor space with deeper sliderooms, wider sofas in rear lounge models, and space saving sliding pocket doors into the bathrooms…all at a shorter towing length. Heavy duty I-beam main rails are placed further outward on the chassis. This wider rail placement provides a more stable jack stance, and allows for the slideroom gearpacks to be enclosed inside the frame rails (rather than outside).

MORryde CRE3000 Suspension - When it comes to suspension performance, it’s all about suspension travel. Increased travel means smoother towing, improved towability and better protection from damaging road shock.

Cooper Tires - 17.5” All-Steel H-Rated Tires. Chip Guard: Protects from chips or cuts. Scrub Guard: Minimizes wear from starts, stops, tight turns and curb impacts. Speed Rating: 75 MPH. Load rating: 4,805 LBS

Stealth 3+ AC - Run Three 15K ACs at the same time! We combine high efficiency AC’s and an energy management system to achieve the perfect balance of efficiency and power! Add an optional 3rd AC for Maximum Cooling Power! Ultra Quiet: up to 2X quieter than the competition. Maximum Available Cooling Power: dual 15,000BTU A/Cs and an optional 3rd A/C. Airtite Connectors: all duct pieces are securely fastened together using special connector brackets. 23% MORE AIRFLOW than average of leading competitors.

Solar Package - Solar Power now comes STANDARD. Camp longer and in more places with the factory-installed 330W Roof Mounted Solar Panel, 50 AMP Charge Controller with Bluetooth Module, Inverter Prep, (2) USB Dock Ports, and 20 cubic foot 12V Refrigerator standard on all Solitude Fifth Wheels. No camping spot is off-limits. Just add batteries and go. Included in the standard solar package for Solitude Fifth Wheels: 330W Solar Panel, 50 AMP Charge Controller, and 20 cubic foot 12 Volt Refrigerator

Constructed to a Superior Standard 

  • Thermal Roof Design (R-40) - Fiberglass insulation and a layer of radiant foil insulation cover the roof. Grand Design goes further by extending both insulation layers the full length of the roof and around to the bottom of the front cap. To maximize the effectiveness of the insulation, a vented attic allows condensation to escape the roof structure.

  • Full Laminated Walls (R-11) - Sidewalls, rear wall, slideroom endwalls and slideroom roof are all welded aluminum framed and laminated with rigid foam insulation. Many others use wood framing and soft fiberglass insulation in the rear wall and sliderooms that can settle over time and leave uninsulated air gaps.

  • Triple Insulated Main Floor (R-45) - The underbelly is lined with a radiant foil insulation barrier (Layer 1) and then covered with fiberglass insulation (Layer 2). The main floor enhances the R-Value with yet another layer of fiberglass insulation (Layer 3).

  • Rail-Tite Underbelly Seal - Rigid aluminum rails are fastened around the perimeter of the underbelly to keep the corrugated barrier up tight against the frame for a better seal from the elements.

  • Insulated Gooseneck - A layer of fiberglass insulation under the gooseneck is a place often forgotten by others.

  • Heavy Duty Insulated Baggage Doors - 1.5” Rigid Foam insulation lines the inside of our heavy duty baggage doors.
