I have an 05 and it is a great truck a friends has the 03 HO with 285K miles and never had a problem, and he pulls with it almost ever day as he moves travel trailers all over west coast.
as for the add in stuff other then exhust i would stay away from it.
if you want more power change injectors to the boat ones you will pick up 75 horse power and about the same in torgue
and dodge will not know unless they pull a injector
