The difference that matters

At roughly 31 ft and 8,600 to 8,900 lb dry, these toy haulers tow alike: hitch weights are 1,400 and 1,500 lb, GVWRs 13,000 and 13,995 lb. The Momentum 25G has a 13.5 ft garage, two slides and sleeps six, with an outside kitchen, a 30 gal fuel station, 220 W of solar and an R-40 roof with R-7 walls.

The Trail Series 25TRX is equipped for remote, cold camping. A Cummins Onan 4K generator comes standard, along with 400 W of solar, a 40 gal fuel station, a fully enclosed and heated underbelly and 6,800 lb axles on load-range G tires. Its ramp is rated at 3,000 lb and it carries 100 gal fresh against 90.

The Grand Design sleeps six. The Outdoors RV stands taller at 13.2 ft against 12.3 ft, worth checking against a garage or storage bay.

Grand Design Momentum G-Class 25G: A family who want two slides, six berths and an outdoor kitchen alongside the garage.
Outdoors RV Trail Series 25TRX: Riders heading to high or cold country who want a generator, more solar and heavy-duty axles from the factory.
