Play Hard. Rest Easy. - The Momentum series has truly raised the bar when it comes to Toy Haulers. With plenty of space for taking it easy and a garage for leaving the mess, the Momentum was meant for living well and playing hard.

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).

Dovetail Entry - Dovetails ensure you have a longer ramp and softer angle for loading your toys.

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) - 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) - 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).
1.5” 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.
