The OP4 is for somebody who wants to get way out there without towing a huge camper. It’s only about 3,100 pounds dry, but once you open it up, you’ve got a huge inflatable tent, multiple sleeping areas, a full outdoor kitchen, refrigerator, optional hot-water shower and serious off-road suspension. You get the camping experience without giving up the ability to take your trailer down roads where a traditional travel trailer simply can’t go.
