Long Bed vs Bigger Overhang - off - roading

13 years experience with a 10'-11" bigfoot TC on 4 door dually used often on BLM and forest roads in colorado mountains and more that hangs 3 feet out the back of 8' box and has extended hitch and side boxes. Ground clearance is not an issue, height is (carry a pole saw) weight of 12,000#s is a lot. Rear diff on heavy duty trucks hangs low. Need taller tires which will reduce gear ratio. We drag ours occasionally. never been stuck, but it tips and leans a lot! Punctured one of the duals on a fairly steep rocky road once. It was a 8 ply michelin at 80% tread and the rock tore a hole right through the middle of the tread. Instantly flat. Had it been a steer it would have been a challenge. Not sure we could have changed it on the grade we were on. Was able to limp to a flatter section. Not sure the same could be said if on a steep hill with drop off like those pics. In which case one might not be able to go forward or reverse. A big camper is heavy. Make sure you have a decent jack that can lift any corner loaded and lug wrench and spare. The factory mechanical screw jacks have great lift power. More than many homeownner floor jacks. When we had the flat, a crew of atvs came out of nowhere and then went back and grabbed a 2 ton floor jack they had at their camp. It would not lift it. The factor screw jack did. A hydraulic bottle jack is next best with a wood block to keep it from sinking out of sight. I recommend carrying 1.5 foot long 2x6/2x8s and foot or so long 4x4 solid wood blocks. Works for wheel chocks, making a dip a bit less if need and can build ramp on to the 4x4 for leveling. Small shovel not a bad idea either. I agree with whom said get an older aluminum lighter lance and try it. Or just go big - Bigfoot. we love
