This problem is rampant is Dodge vehicles. Had a Ram 1500 with similar issue, but this one is in such a bad place to work on, the plastic bumper needs to come off to really work on it. I've only had the vehicle since the Summer 2016, bought it used. Really don't have a lot of money to repair it, but I am usually really anal about keeping my vehicles clean so this really upsets me.

Both rear quarters rust through on the wheel arch and beyond. Also I have noticed both rear doors starting to rust and bubble through as well.
