I'm planning a trip to the National Seashore in TX and there is a 4WD only area that I've traversed before without issue. It is very soft sand that you can feel your vehicle sliding around on. I aired down and though I would spin tires on take off, never really felt like I was getting stuck. However, I wasn't hauling my trailer. I'm not sure what the effect of my AT will be. Anyone with experience doing this?
