That's the problem Mark, most of them I've seen were not
properly installed. All that is supplied with the cheaper
cranes are a couple pieces of angle iron.
Don't know what they do to install a fifth wheel but I'll bet
it's mounted off the frame and not hung on the few bolts that
hold the bed down.
By the way, I have no intention of installing one of these on
any of my trucks, just curious about them.
