• 2026 XT16HR ISLAND Off-Grid Extreme

This unit is built to order.

The MDC XT16HR Island Off-Grid Extreme is a true overland travel trailer, built for those who crave rugged off-road capability without sacrificing modern comforts. At just over 22 feet in length and under 5,500 lbs dry weight, it strikes the perfect balance of size and towability. With a full cold-weather package, all-season insulation, and one of the most advanced off-grid electrical systems in its class, the MDC XT16HR Island is engineered to go farther and stay longer. Whether you're exploring deep into public lands or setting up basecamp off the beaten path, this trailer gives you the freedom, comfort, and self-reliance to make it happen. Built on a galvanized steel chassis, equipped with X-TRACK independent suspension and a DO35 articulating hitch, this trailer is ready for anything you can throw at it.

The exterior of the MDC XT16HR Island Off-Grid Extreme is all business, purpose-built for overland durability and functionality. The electric 14.3’ cassette awning and fully enclosed annex system expand your living space outdoors, while dual slide-out kitchens (internal and external) give you the flexibility to cook in any environment. You'll find dual 21-gallon freshwater tanks, a 21-gallon grey tank, and all lines are insulated and heated for cold-weather resilience. The 800Ah lithium battery bank is powered by 700 watts of rooftop solar, with ports for an additional 600W of portable panels—keeping your rig charged and ready. With rugged aluminum wheels, mud-terrain tires, and heavy-duty drop-down stabilizers, this trailer stays planted wherever you decide to set up camp. Add in ample storage, a wall-mounted exterior shower tent, and a rear-mounted ladder for roof access, and the XT16HR Island can take you further in style.

Step inside the MDC XT16HR Island and you’ll see what separates this rig from typical off-road campers. The centrally positioned queen bed offers comfort and accessibility, while oak timber-style counters and sleek matte black fixtures give the space a premium, modern look. The full bathroom includes a Thetford cassette toilet and separate hot/cold shower—no more compromising hygiene in the backcountry. With a well-equipped kitchen featuring a stainless steel 3-burner cooktop, microwave, and a 5.3 cu. ft. compressor fridge, cooking indoors is not just possible—it’s enjoyable. Truma climate systems (AC and propane furnace) make this a true four-season rig, while LED lighting, dual-pane windows, and high-end cabinetry round out a smart, stylish interior. This space is made for real-world off-grid living.
