WILL MY TRUCK TOW IT

It depends on your truck and load. A Sales Coach will check yours.

Towing depends on your truck, how it is equipped and how you load the trailer. Compare your truck’s tow rating to the fully loaded weight, not the dry weight. A Sales Coach will check your setup.

01 / Power

More Power

One of the most robust off-grid power systems available in any trailer under 6,000 lbs dry. Paired with a Renogy 3000W pure sine wave inverter, you can power A/C, outlets, and all appliances completely off-grid—with ports for up to 600W of additional portable solar.

02 / Bathroom

Full Bathroom with Separate Toilet and Shower

A dedicated dry bath inside a compact overland trailer is rare—especially with hot/cold water and a Thetford cassette toilet. This gives you independence from campgrounds or external facilities.

03 / Kitchen

Dual Indoor + Outdoor Kitchens

Cook wherever the moment takes you. A full internal kitchen with a stainless 3-burner stove, microwave, and fridge pairs with a slide-out stainless steel external kitchen—both with hot/cold running water.

04 / Chassis

Heavy-Duty Off-Road Build with X-Track Independent Suspension

Built on a galvanized steel chassis, it features Cruisemaster DO35 hitch, ARK jockey wheel, TOUGH TRAX dual shocks per wheel, and 16” all-terrain tires—engineered to handle real-world overlanding, not just gravel roads.

WHAT COMES WITH IT

YOU DON’T JUST BUY A TRAILER. YOU JOIN THE ROAMERS.

Roamers are the people who buy from ROA OFF-ROAD and camp with us.

Why Roamers buy here

“The dealership makes a difference. I talked to off-road dealers that specialize in this. They couldn’t tell me anything about the trailer specifics. Hey, it’s got a great suspension. Why? And they couldn’t tell me. So in this case ROA knew all the answers, and why.”

GregRoamer

ROAMER RALLY AND ADVENTURES

The Roamer Rally at ROAMERLAND, near Panguitch, Utah, and Roamer Adventures through the year.

“I have learned more over the last three days that I’ve been here than I could have probably learned over five, 10 years on my own.”

Troy, Roamer

HANDOVER DAY

A handover specialist walks you through every system when you pick it up.

“The biggest thing is the walkthrough… that was an all-day walkthrough going through every single component.”

Michael, Roamer

CUSTOM MODIFICATIONS

Our shop fits the upgrades and modifications that make the trailer yours.

“You’ve been absolutely fantastic with the upgrades that I want to do. I know I’ve pushed your limits a few times.”

Justin, Roamer

TECH SUPPORT

Call from the road and someone who knows your trailer walks you through it.

“We’ve had our fridge die in the middle of the desert… you go into panic mode, you call ROA… And then they walk you through and you do the checks and everything calms down.”

Maribel, Roamer

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.

Outside.

Read about the outside

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.

Inside.

Read about the inside

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.

Straight Answers

Ask your own question

Will my truck tow the XT16HR Island?

It depends on your truck, how it is equipped and how you load the trailer. Fully loaded it can weigh up to 6,147 lbs, with about 530 lbs on the hitch, so compare those to your truck's ratings, not the dry weight. A Sales Coach will check your setup.

What powers it off grid?

800 Ah of lithium battery, 700 W of rooftop solar with ports for 600 W more of portable panels, and a 3,000 W pure sine inverter that runs the air conditioner, the microwave and every outlet without hookups. How long it lasts depends on what you run and how much sun you get.

Does it have a real bathroom?

Yes. A Thetford cassette toilet and a separate hot and cold shower, plus an outdoor shower with its own tent.

What does it carry for cold weather?

Heated tank pads, insulated water lines, a wet bay heated from inside, an anti-freeze kit for the water heater, self heating batteries, dual pane windows and an 11,500 BTU Truma furnace. Ask a Sales Coach how it suits the trips you have in mind.
