They're also pretty hard to twist. Keep that in mind. If it's twisted that bad, that's a pure parts machine. Lord only knows what else you'll find after working on it.
Unloaded! That was what I was thinking maybe happened and whole rig is now bent out of shape from that! See if you can at least roll it off the trailer on level and get better look, and underneath too. $500 too much, maybe the $300 IF not twisted frame. These frames are like a 3" x 10" channel and pretty hard to straighten one of those out.
