Last weekend we flat towed our Jeep TJ for the first time to Quemado Lake with the back seat removed (just me and the wife this time) and it was great to have a run around vehicle and an enclosed trailer also.
We also have a 5x10 single axle trailer that can handle 2 enduros and gear or 1 4 wheeler and some gear but, the 5x12 Big Tex tandem with 3500lb axles and 1 brake axle allows for 2 4-wheelers, firewood, gear, ect ect ect without being overloaded and also serves as a dolly (perfectly) to get my camper into the shop (10ft door) for winter storage:)
I don't think I'll ever leave without the Jeep again, just ordered a Smittybilt roof rack so I can load it with even more gear, 300lb capacity
