I am going to be starting some cab rust repair this coming weekend and I've been pondering removing the cab. Ideally the easiest access would be to rest the cab on it's back to deal with replacing the outer sections of cab supports; however someone on another forum said it's not a good idea because the cab wasn't made to rest on it's back and you can cause it to shift. The cab is actually pretty solid. The only rust it has is the driver rocker and cab corner and the very outer few inches of the cab supports. What would be the best thing to do to deal with this? Thanks
