2015 Grand Design Momentum 388M Toy Hauler--14' Garage, 3 A/Cs, Generator, Office Conversion & Washer/Dryer

This 2015 Grand Design Momentum 388M fifth wheel toy hauler combines luxury living, flexible workspace, and a spacious 14-foot garage into a versatile coach designed for extended travel, full-time living, or hauling your favorite toys. Built with Grand Design's quality construction, this Momentum features three slide-outs, three roof air conditioners, hydraulic auto-leveling, a Cummins Onan 5.5kW gasoline generator, and a Reese Goose Box hitch upgrade for smoother towing.

The living area offers opposing slide-outs that create an open floor plan with comfortable seating, entertainment center, fireplace, and abundant cabinetry throughout. Large windows provide natural lighting while the residential layout makes the coach feel spacious whether relaxing or entertaining

The kitchen provides generous countertop space, residential appliances, abundant cabinet storage, and a large refrigerator, making meal preparation convenient whether traveling or staying long-term. The dining area blends seamlessly into the living space while maintaining excellent storage throughout.

Rather than the original factory king bedroom, this Momentum has been converted into a dedicated office and workspace complete with built-in desk, shelving, and storage. This unique conversion makes the coach especially attractive for buyers who work remotely or desire additional hobby or craft space while traveling. Buyers seeking a traditional bedroom should note that this area has been customized from the original factory configuration.

The bathroom provides a spacious shower, vanity, medicine cabinet, and residential conveniences with practical storage for extended trips.

The 14-foot garage remains one of this coach's standout features. In addition to providing generous cargo capacity for motorcycles, ATVs, golf carts, or other toys, it also includes a GE Profile all-in-one washer/dryer, adding convenience for extended travel and has a half bath. The garage easily adapts as cargo space, additional living area, workshop, or guest accommodations depending on the owner's needs.

Outside, the Momentum features fiberglass construction, hydraulic self-leveling, a large power awning, abundant pass-through storage, and the upgraded Reese Goose Box hitch. The front compartment houses a Cummins Onan RV QG 5500 gasoline generator with approximately 130 hours. The roof was accessed and photographed during the inspection, with three roof-mounted air conditioners, vents, antennas, and rooftop components appearing intact at the time of inspection.

Please feel free to call, text or email with your questions, to schedule an appointment to see it or to make an offer.

Buyers are encouraged to complete their own personal and/or professional inspections to verify overall condition and operation of all systems.
