I moved to Upstate NY from Arizona (actually via Washington - I can't read a map!) with my rust free 91. I know the salt will eat it, but...oh well.
I fogged the chassis of the truck with two big cans of WD40 last fall, a couple of times, and I hit the car wash weekly in the winter to blast the crap off underneath. I don't know if it helped at all, seems like it did.
200k miles...I guess it will die before it rusts out.
