The funny trailer stuff just keeps up today. My neighbor allows a tree service to dump wood and brush on his land. Problem is, they have dumped so much brush in a few spots over the past couple years, they can't tell where the solid ground ends and a steep eighty foot drop begins!
When I got home from running errands, I saw them trying to yank this 10400# trailer up a hill with a mid-90s F350 SRW gasser. None of the trailer's wheels were on the ground and they didn't even bother to remove the load! This picture is, if you can believe it, after they had made quite a bit of progress pulling it up:
They did eventually get it out (by making running starts with the trailer chained to the front bumper of the F350) but not before bending the plate the jack is mounted on and doing some more damage to its axles ("they were already bent anyway.") I had to get a floor jack from my garage so they could get the tongue up high enough to get it back on the F350 after trashing the jack. I had an adjustable drop hitch in my truck but I was afraid to let them use it!
Incidentally, they pull this thing around town, loaded full of loose brush and big chunks of trees, with no lights, no brakes, no load-securing, the wrong size towing ball, and a bent ball mount. At least they use the safety chains.
