    AI summary

    The front-to-rear layout here is what sets this one apart. The King bed suite up front gives you a private retreat completely separated from the rear living area, which opens up around a fireplace and rear window that actually makes the space feel grounded rather than like the back of a trailer. DRV builds the 40KSSB4 with serious bones: 3-inch floors, 3¼-inch walls, Kodiak automotive disc brakes, and a hydraulic leveling system that handles setup automatically. A kitchen island and washer/dryer add the kind of residential functionality that makes long-term or full-time living genuinely comfortable. Owners consistently describe it as an apartment on wheels, and the construction spec. R29 floor insulation, Azdel fiberglass, Monsanto vapor barrier. Backs that up in any season.

    New Ford F-350, RAM 3500, Sierra 3500, or bigger

    Based on overall weight and weight directly on tow vehicle's hitch and a new model tow vehicle. Please consult with a professional.
