You must of had some acid / salt rain or something on your 2003. You are the only one who has had a problem that I have seen with a 2001 or newer.
But it is prabably our destiny.
We like to go down and dry camp on Padre Island on the National Sea Shore. 10 days with the salt spray and everything with iron and my window awning brackets all started to pit, rust etc. etc.. We met some Airstreamers down in South Padre at the County Park last winter who stay there for a couple months in the winter. Absolutely destroys the trailer. After 3 weeks on the beach we headed for the desert. I soaked all the iron parts and brackets with constant wd40 and this summer will brush paint my tongue and feet.
