Hey Dodge man, sorry for your problems. I too am from west central IL & have an 07 Ram with Cummins. I had mine rustproofed and undercoated when it was new so hope the rust will stay away a long time. A friend bought an 06 Ram last year & it started rusting shortly after he bought it. He took it to Cavanaughs in Monmouth (my dealer) & they told him there was a problem with rust over the rear fenders due to a design problem. Dodge paid to have the repair done at a body shop they recommended. Its probably to late for you to collect on that after the fact, but it might help someone else. I thought that was good of Dodge to stand behind their product like that, especially since he bought it used from an independent dealer.
