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!
