Checked out my dads 01 this weekend, an there was a small amount of rust along the bottom lap weld. I was shocked to see this on this new of a truck. all of the drain plugs, were still in, but it looks as if even if they were removed, they arent at the lowest point, and water would still stand a 1/4 in deep. , until it ran to the end drains. This particular rust issue seem s to be with the metal lap,( at very bottom) and not drain plug related. What is chryslers rust warranty, the truck has 42000 miles on it, and he is the second owner?
