2025 Grand Design Momentum G-Class TT 25G

Go big, conveniently.
The all new Momentum G-Class is lighter without sacrificing any comfort or spaciousness — thanks to our tall ceilings and slide outs. With all of the quality, innovation, and functionality that our family of Momentum owners love, it's everything you need and nothing you don’t.

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

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.

MORE TIME. MORE PLACES.
SOLAR POWER NOW COMES STANDARD
Camp longer and in more places with the factory-installed 220W Roof Mounted Solar Panel, 30 AMP Charge Controller, and 12V Refrigerator 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*.
