turns out backing in a loaded F550 mason dump into mud/**** isnt such a good idea
theres a biological company at my work cleaning up all the lily pads/the muck at the bottom of the lake...so we have to move it after they dump it on the shore. this stuff is worse than the mud youd find anywhere in teh woods, its like driving on a lake bed that just recently "dried" up
but, once i dumped the truck, and put it in 4x4 low range....all 6 wheels hooked up and got me out, albeit sideways
