Rocker panels and cab corner rusted out, was able to push my finger through the paint. Had them replaced in spring of 2014. Replaced a rear brake line at the time due to ease of access with box removed. Spring of 2016, I had a front brake line fail while approaching a stop sign. Had enough braking left to stop int time. Replaced front brake lines due to rust. Rear section of frame is rusting along with lines on diesel fuel cooler and front control arms. This is not my primary vehicle. We use it for trips and to pull our camper. I have tried to drive it as little as possible on salty and sloppy roads. The paint on outside and the interior looks great. I am concerned on how much longer it will be safe to drive and tow.
