Goodyear® Endurance Tires

Good Year Endurance Tire

Goodyear Logo

A DEPENDABLE TIRE DESIGNED TO HELP YOU TOW WITH CONFIDENCE.

Trailer tires designed with durability in mind to help make towing a trailer less stressful by reducing impact-related failures. Special purpose trailer tires are not intended to be used on cars or light trucks. Endurance trailer tires feature a rounded profile to help cushion the trailer’s ride, and the symmetric tread design with closely spaced ribs provide constant rubber-to-road contact for straight tracking

Good Year Endurance Logo

101” Wide Body SuperChassis

Grand Design Exclusive Super Chassis Design

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.

Solar Package

MORE TIME. MORE PLACES.

SOLAR POWER NOW COMES STANDARD

Camp longer and in more places with the factory-installed Dual 220W Roof Mounted Solar Panel, 30 AMP Charge Controller, and 2,000W Inverter standard on all Momentum G-Class Travel Trailers. No camping spot is off-limits. Just add batteries and go. Camp where you want, when you want*.

INCLUDED IN THE STANDARD SOLAR PACKAGE FOR MOMENTUM G-CLASS TRAVEL TRAILERS:

*We may have gotten a little excited, please camp safely. Follow all laws and abide by no trespassing signs, you know what we mean.

Constructed to a Superior Standard

Thermal Roof Design (R-40)*

Thermal Roof Design

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-7)*

Fully Laminated Walls

Full Laminated Walls (R-7)*

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-40)*

Triple Insulated Main Floor

Triple Insulated Main Floor (R-40)*

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

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).

Vented Attic

Vented Attic

To maximize the effectiveness of the roof insulation, a vented attic allows condensation to escape the roof structure.

Here is what customers have to say...

★★★★

I enjoy the simplicity and the build of the unit. You can tell a lot of thought was placed in setting up the design. It has the filling of a small apartment on wheel. Following and handling is superb I enjoy the comfort that it offers with residential appeal and large storage places.

This is our second Grand Design. First one being a Solitude and this one a Momentum. This is our 5th one that we have owned. All of them have been fifth wheels. 3 of them have been toy-haulers. We are really enjoying the design of the 395ms-r. For us the floor plan feels warm and inviting. Comfortable living while out on the road is an understatement. The quality of our GD far exceeds that of the other RVs we looked at purchasing this time. The systems are well thought out and good design. Ken

We recently purchased a Grand Design Momentum 376THS from McClain's RV in Fort Worth. Our expectations were exceeded by McClain's RV and Grand Design. We searched for two years and settled on the 376THS design because it met our desired requirements. Our unit was delivered two plus months earlier than expected. We started with a 5-week shake out trip and learned how much we enjoy the 376THS. Thank you to McClain's RV in Forth Worth and Grand Design for creating the 376THS.

This is now our second GD trailer. We were looking for a Toy Hauler and after watching far too many YouTube reviews, finally visited our local dealer who thankfully has an excellent full lot of various makes. We made a very conscientious decision to start at the lower end of what we were looking for and move up in various brands, costs and sizes before visiting the Momentum we knew we would like. As we thought, walking into the GD trailer after seeing the others was night and day!
