Just to raise the dead (thread) the other day I bent my adapter (identical to the one in post #35)! There is this thread, and another (I think on SS, I'm searching...) about bending these things. The other thread the guy posting says "doesn't know what happened" and I though, that's very odd, he must have noticed something.
Well I did it (exactly like him) and I have no idea why it bent. Was moving my M-200A1 with a MEP-004, and did hit a snow bank but not hard. Only hard enough that I thought, "Perhaps easier to just drive out and pull is forward so I can have some momentum." Did that, and drove right through the snow. Later I looked and it was bent--a six inch wide piece of 1/2" steel, bent without me feeling a thing.
I'd swear off those adapters (it is the one that gives the maximum lift) but without it I can't easily get the trailer on the truck or the Hummer.
