Looks bent up from being worked but seems pretty solid. This one of the beds converted to a trailer?
Yes. The frame upon which it sits is a frame where the one on my truck the bed came off. I believe it was an 84+, because it was blue and white with horizontal side marker and the tail lights had a later style sockets.
It was originally on my frame, replaced for rust and dings.
The bedsides are the worst.. I actualy have bedsides from a 77 that are also rusty but less overally mangled. But I would hate to take it and put it on my truck, it would see less good use sadly. And the one on my truck is... unlikely to do okay after its removed. maybe, i guess i cant know.
