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

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.

Here is what customers have to say...

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!

We absolutely love our new Momentum 397th-r. This is our second Grand Design Momentum and we haven't had any issues with either unit. The fit and finish on our new toy hauler has exceeded our expectations and we are constantly getting compliments while out on the road on the full body paint. We are part of the Grand Design family for life! We would never consider another brand of RV ever! You just can't go wrong with the quality and workmanship on these rigs.
