Exclusive Grand Design Super Chassis Design
101" Wide Body Chassis
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.
Wide Rail Design
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).
No Wheel Wells
A true toy hauler with no wheel wells to maximize cargo option. Not to mention more floor space for camping.
Dovetail Entry
Dovetails ensure you have a longer ramp and softer angle for loading your toys.

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.
Full Laminated Walls (R-11)*
Sidewalls, ramp door, 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 sliderooms that can settle over time and leave uninsulated air gaps.
Triple Insulated Main Floor (R-45)*
Triple Insulated Main Floor (R-45)*
The underbelly is lined with a radiant foil insulation barrier (Layer 1) and is then covered with fiberglass insulation that wraps all the way up the sides of the frame rails (Layer 2). The main floor enhances the R-Value with yet another layer of fiberglass insulation (Layer 3).
Triple Insulated Garage Floor (R-40)*
Triple Insulated Garage Floor (R-40)*
While many toy hauler garage floors are NOT insulated, our exclusive garage floor design provides 3 layers of insulation. A base layer of radiant foil insulation (Layer 1) is topped with fiberglass insulation (Layer 2), and finishes with a second layer of radiant foil insulation on the underside of the garage floor (Layer 3).
Insulated Baggage Doors
Rigid Foam insulation lines the inside of our heavy duty baggage doors.
Vented Attic
To maximize the effectiveness of the roof insulation, a vented attic allows condensation to escape the roof structure.
Insulated Gooseneck
Radiant foil insulation under the gooseneck is a place often forgotten by others.
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.
