Hello all, brand new to the site. I’m looking into buying a 7.3 power stroke and have found one local to me for a killer price. 230k on the clock, downside is rust. Rust in the rear doors, cab corners, and bed. The drive train runs good. The one thing I’m majorly concerned about is that the bed sits lower than the cab on one side(about an inch to 2 inches, very very slightly on the other (maybe a half inch) My thought is cab corners but wouldn’t that make the cab sit lower? Then I thought it could be the bed rails rotted out… I’m at a loss and have tried to find other problems on the forums but have had no luck. What do y’all think?
