The 2020 Grand Design Momentum 381M is a luxurious and versatile M-Class fifth-wheel toy hauler, designed to combine high-end living with the ability to transport recreational vehicles. It features a rear garage with Tuff-Ply flooring, tie-downs, and a ramp door, a half-bath in the garage, a master suite with an elegant bath and amenities like 3 A/Cs, a generator, a fuel station, and a central vacuum system. The 381M is a lighter option than the G-Class series but still offers extensive features, extensive insulation for four-season use, and options for power leveling and multiple air conditioning units.
