Description

The Grand Design Momentum G-Class 31G is a powerhouse toy hauler designed for thrill-seekers who crave adventure without sacrificing luxury and comfort. With its spacious garage, dual bathrooms, and well-appointed living spaces, this toy hauler is ready to elevate your outdoor experiences.

Key Highlights of the Grand Design Momentum G-Class 31G:

Bath and a Half: One of the standout features of the 31G is the convenience of having a bath and a half. The master suite includes a private entrance to the full bath, which is also accessible from the main living area. Your guests will love the half bath located in the separate garage, offering them privacy and convenience, especially after a day of riding or exploring.
Dual Entry: This toy hauler features dual entry doors, providing easy access to both the main living area and the garage. This setup enhances privacy and allows for smoother transitions between activities, whether you’re coming in from an adventure or just stepping out to enjoy the evening air.
Theater Seating: After a day packed with action, relax in the theater seating located in the slide-out. This cozy spot is perfect for unwinding with a movie or simply enjoying the company of your fellow travelers. The seating arrangement provides a comfortable view of the entertainment center and a great spot to socialize.
18' Power Awning with LED Lights: Extend your living space outdoors with the 18' power awning. Whether you’re looking to relax in the shade during the day or enjoy the ambiance of the LED lights at night, this awning makes it easy to set up a perfect outdoor lounge area.
13' Separate Garage: The 13' garage is the heart of the Momentum 31G, offering ample space to transport your toys. The garage is versatile, serving as both storage and an additional living or sleeping area once the toys are unloaded. With the Happi-Jac sofas and an optional top bed, the garage easily transforms into a comfortable space for guests or a casual hangout spot.
Universal Docking Station: The universal docking station simplifies your setup and maintenance routines, centralizing all your hookups and controls in one convenient location. This thoughtful design feature ensures you can quickly get your RV up and running, leaving more time for fun and relaxation.

Built for Year-Round Adventures:

The Momentum G-Class 31G is equipped with an Insulation Package that makes it suitable for all-season camping. With a heated and enclosed underbelly, suspended tanks, and cabinet-mounted heat ducts, this toy hauler is ready to keep you comfortable in any weather. The high-capacity furnace and moisture barrier floor enclosure further enhance its ability to maintain a cozy interior environment, even in colder climates.

For your off-road adventures, the 31G includes a 30-gallon fuel station with both interior and exterior gauges, so you can keep your toys fueled up and ready to go. The 2,500-LB tie-downs anchored into the chassis ensure that your gear is secure during transport, while the dovetail rear end makes loading and unloading a breeze.

Experience Adventure in Style:

The Grand Design Momentum G-Class 31G combines rugged functionality with luxurious features, making it the ideal choice for those who love to travel in style.
