Exactly! I got my two-wheel drive truck stuck up to the hubs on all four wheels in desert sand, which means the entire drive line and the oil pan were dragging along with both axles buried, and I got that out with a shovel and some scraggly branches.
It took about six hours and I had to spend the night, had the rear bumper up against a rock mountain at one point, but I drove it out.
I’ve been stuck in many substances.
You know what the worst is?
Pumice.
You just sink down into it as if it were packing peanuts.
Lesson: stay away from defunct volcanoes.
