Grand Design Momentum 25G: The Wide-Body Adventure King
The 25G is famous for its dual-slide layout—one in the kitchen and one in the bedroom—which creates a remarkably open living space once the toys are unloaded. Because it features a 13' 6" garage with no wheel wells, you have a completely flat floor for loading and living, making it one of the most versatile 30-foot trailers on the market.
G-Class Luxury & Garage Highlights
13' 6" Versatile Garage: A true toy hauler with no wheel wells to navigate. It features 2,500 lb. tie-downs anchored directly to the chassis and the Happi-Jac® electric bunk system, which provides a power queen bed above and convertible sofas/dinette below.
Modern Chef's Kitchen: Thanks to the kitchen slide-out, you get a residential feel with solid surface countertops, a deep-seated stainless steel sink, and an 8 cu. ft. refrigerator.
Master Suite with Wardrobe Slide: Unlike many toy haulers where the bed feels like an afterthought, the 25G features a front queen bed slide that opens up the room to include a large mirrored wardrobe and drawers.
The "Patio Lifestyle": The rear ramp door is more than just a loading dock; it transforms into a fenced-in patio deck with an optional power awning, creating a massive outdoor elevated lounge.
Rockford Fosgate® Audio: Standard with a premium 500W+ sound system including a powered subwoofer and app-controllable interior/exterior speakers.
15,000 BTU "Race Track" A/C: This unit utilizes a specialized circular ducting system ("Race Track") that ensures even, high-pressure cooling from the front bedroom all the way back to the garage.
On-Board Fuel Station: Includes a 30-gallon fuel tank with an exterior pump and an interior/exterior fuel gauge, so your toys stay gassed up even in remote locations.
Oversized Tank Capacities: With a 100-gallon fresh water tank, the 25G is built for extended boondocking sessions.
SuperChassis" Construction
Grand Design’s G-Class is built on a specialized frame meant for heavy loads and rough roads:
101" Wide-Body SuperChassis: A full 5 inches wider than standard trailers, providing deeper slides and more "elbow room" in the bathroom and kitchen.
Dovetail Entry: The rear of the chassis is "dovetailed" to provide a lower approach angle, making it much easier to load low-clearance bikes or cars.
Insulation Package: Features an enclosed and heated underbelly with suspended tanks, plus a double-insulated roof and front cap (R−40 rated) for comfortable four-season use.
