I notice a ton of 2004+ Dodge Rams with rust over the rear wheel wells. Oddly I see plenty of late 90s Rams that have no rust. So was this a design problem or problem with the galvanization of the steel? If so, any idea if Dodge has resolved it? I just bought a 2014 Ram and would be disappointed if it started rusting before it was 10 or 12 years old.
