No you're kidding yourself here, chrysler workmanship was never going to go the extra mile, the body shop even said from the start,the inner rust is what gets these trucks and makes bringing them back from the dead so expensive.
My RC was a solid truck, looked like minor rust repair, you can't leave raw metal anywhere and think it wont develop rust and won't spread.
The least a person could do on these trucks without total disassembly, is to maybe find a way to por 15 the inner structures through the bottom drain plugs and through the tail light openings. They weren't even sealing the seams all the way through or the entire length of the seams.
It doesn't matter if it spent it's life in the sahara desert, one car wash and the rust is started.
