The 2023 Grand Design Momentum 397TH is a luxurious and versatile 44?ft?2?in fifth-wheel toy hauler engineered for adventure and comfort. Built on a rugged 101-inch wide-body aluminum cage chassis and triple 7,000-lb axles with MORryde CRE3000 suspension and ABS, it tows smoothly and handles well under load.

Inside, it offers a separate 13′?6″ garage with gas/oil-resistant Tuff-Ply flooring, Nike-rated flush tie-downs, side vents, and an auxiliary 60-gal fuel station—ideal for ATVs or a compact car. The living area features a show-stopping kitchen island, bar-stool seating, 49″ LED TV, fireplace, recliners, and a freestanding table, all amidst hidden-hinge hardwood cabinetry and accent LED lighting.

The front bedroom includes a queen bed (king optional), a full walk-in closet, and washer/dryer prep. Two full bathrooms (one with sunken fiberglass shower/tub) add luxury and convenience. Utility essentials include a 140-gal fresh tank, 104-gallon gray and black tanks, dual LP tanks, 50-amp service, and optional Onan generator and solar package with 20-cu?ft refrigerator.

Standard features like 3 power awnings, 6-point hydraulic leveling, weather-rated insulation (R-45 floor, R-40 roof), and multiple exterior TV options ensure comfort and usability in any season. With upscale amenities and extreme durability, the 397TH delivers spacious luxury in a rugged package for up to nine sleepers—truly where extravagant living meets outdoor ready adventure.
