Used 2022 Grand Design Momentum 399TH – Luxury Toy Hauler Meets Family Adventure

Turn every getaway into an unforgettable experience with the Used 2022 Grand Design Momentum 399TH, a top-tier toy hauler that combines residential comfort, generous living space, and serious utility for adventurers who refuse to compromise. Whether you’re hauling ATVs, motorcycles, or outdoor toys, this Momentum model delivers strength, style, and comfort in one striking package.

Spacious, Functional Interior Designed for Real Living
Step inside and be impressed by the expansive floorplan that feels more like a luxury home than a traditional toy hauler. The sizeable living area features stylish seating, a slide-out that expands space for comfort, and wide panoramic windows that draw in natural light and scenic views. Plush furniture creates an inviting environment for relaxing, socializing, and making every moment on the road feel special.

The fully equipped kitchen rivals many residential spaces. With a residential-size refrigerator, three-burner stove, oven, microwave, and substantial counter space, meal prep becomes a joy rather than a chore. Thoughtful storage solutions keep cookware, utensils, and pantry items neatly organized, and the dining area offers plenty of room for meals, game nights, or planning tomorrow’s adventure.

Toy Hauler Flexibility Without Compromise
One of the standout features of the Momentum 399TH is its spacious garage area—designed to handle your toys and gear with ease. Whether you’re loading up off-road vehicles, bikes, or camping gear, this trailer’s oversized garage delivers durability and convenience. The adjustable tie-downs and ramp door make loading and unloading a breeze, while integrated storage keeps gear secure during travel.

The front master suite offers a private, restful retreat with a comfortable bed, generous storage, and a layout crafted for rest and relaxation. The full bathroom includes a shower with skylight, vanity, and toilet, giving you all the comforts of home no matter how rugged your journey. Interior and exterior storage compartments throughout the coach keep your belongings organized and accessible.

Entertainment and Comfort on Every Trip
With climate control systems to support year-round comfort and entertainment options throughout the interior, the Momentum 399TH isn’t just rugged—it’s rich in amenities. Whether you’re hosting movie night after a day in the outdoors or curling up with a book while the world goes by, this toy hauler offers living space that works for families, couples, and adventurers alike.
