I drive a 2003 Cummins and love the truck but I have atrocious rust on both my rear wheel wells, and I need suggestions. I am going Saturday to look at buying a 2005 bed that will fit my truck with 0 rust and 0 dents, but wouldn’t it eventually just have the same problem as every other dodge with the rust? Would I be better off just getting fiberglass bedsides as replacements for my rusted out metal ones? If you have fiberglass bed sides message me and let me know how you feel about them, thanks!
