The 14' 6"" separate garage is more than storage—it’s a flexible adventure zone. With heavy-duty tie-downs, its own half bath, loft sleeping space, and a second exterior entry door, this area adapts easily from toy storage to guest quarters or a private hangout. The rear ramp door converts into a patio, expanding your living space and giving you front-row views of the action wherever you park.

Inside, the main living area welcomes you with theater seating, a cozy fireplace, and a well-equipped kitchen that makes home-cooked meals part of every trip. Whether you’re fueling up before a long ride or winding down after sunset, this space is designed for comfort and connection. Large panoramic windows bring the outdoors in and keep the scenery center stage.

The full bathroom features a walk-in shower with skylight, making cleanup quick and comfortable after a dusty day. Up front, the private master bedroom offers a peaceful retreat with a wardrobe slide, overhead cabinets, and USB charging stations so your devices stay ready for the next adventure.

Momentum G-Class toy haulers by Grand Design are built to explore all year long. The Insulation Package includes a heated and enclosed underbelly with suspended tanks, a high-capacity furnace, moisture barrier floor enclosure, and cabinet-mounted heat ducts for dependable four-season performance. You’ll also appreciate the dovetail rear end, 2,500-lb. chassis-anchored tie-downs, high-capacity water pump, residential cabinetry, and thoughtful comfort features throughout.
