Inside the OP4
Built around the way you actually camp.
AIR Beam Technology
Nine individually valved air beams inflate in under 2 minutes, opening 8 ft ceilings, multiple sunroofs and windows on every side. Waterproof and tested to 70 mph winds. Nothing to bend, snap or leave behind at the last camp.
Off-road and off-grid ready
Cruisemaster DO35-ready chassis with 360° articulation, heavy-duty coil springs and a dual-shock axle, riding on 12 inches of ground clearance. Point it down the two-track and it follows your truck.
Outdoor cooking
Slide-out stainless kitchen with a 4-burner stove, hot-water sink and a 12V refrigerator and freezer. Cook facing the view instead of a cabinet door, and clean up without anyone climbing over the bed.
Gear and toys
Carry up to 500 lbs on the roof rack, bikes, boards, boats and boxes, with GVWR still just 4,400 lbs. Bring the whole hobby, not the shortlist.

OP4 by the figures.

Owner stories
Real adventures.
Real people.
Owners on the trips they actually take with the OP4. Here is what they told us.
“Be warned, when you own one of these, and you walk by it everyday in your garage, you feel kind of bad, like you have an animal pent up in a cage, and you're the reason it can't be out in the wild where it belongs.”
“Traveling more than 5,000 miles and through 15 states, the OPUS performed flawlessly. Some of the highlights were the Badlands, Custer State Park and Devils Tower. We could not stop at any gas station, drive-thru or store without folks coming over to ask about the OPUS.”
“The next day we stopped and signed our name at the Mojave Mailbox. We then took another detour up to the lava tubes and went inside and got some amazing photos.”

Common questions
Everything you want to know.
2 minutes for the AIR tent, and one person can do it alone. Level the trailer, hit the switch, and the onboard compressor inflates all nine air beams at once. There are no poles to thread and nothing to lose in the dark. Pack-down is the same routine in reverse.
GVWR is 4,400 lbs with 352 lbs on the tongue, and the OP4 weighs 3,100 lbs dry. A half-ton pickup, a midsize truck or a body-on-frame SUV rated to 5,000 lbs and up handles it comfortably. Check the tow rating and tongue capacity on your specific vehicle and hitch before you order.
40 gallons of fresh water across two tanks and 2 x 100Ah deep cycle batteries cover a long weekend for a family running the refrigerator, lights, pump and device charging. Add the Zamp 140W solar and the lithium upgrade and you can stretch it well past that. Real-world range depends on the weather and how hard you run the fridge.
MSRP covers the OP4 as it is built on the standard inclusions list: AIR tent and tropical roof, slide-out kitchen, 40 gal water system, twin batteries, king bed extension cushions, off-road hitch and running gear. Title and tax are quoted by your dealer. Everything in the optional column is added at order. The OP4 LE is the same trailer with nine upgrades fitted as standard, from $49,000 MSRP.
Build & Price5 years on structure and suspension. Component manufacturers carry their own terms, and your OPUS dealer confirms all of it in writing before you sign.
