I looked at most of the posts , and almost all that have talked about lack of maintenance do live in the heavy salt states , making comments with out knowable .
I've lived in multiple states , CA. , MN. , to name a couple of extreams ,
While maintenance , will help , it is a minor factor , for those who differ , come to MN. , plow [ almost always in the early am , ] then get home at sunrise to get a cat nap before your regular job , & tell me your going to take the time to ???
When I start to look for a truck , I do not even bother to look in the 5 state area [ MN WS ND SD IW ] I've owned trucks as old as 48 [ the truck not me ] folks from CA. would be blown away by rust here [ I lived there for 15 yrs ] , had a few utility truck that work the cost , less than 1/4 of what happens in MN. - I am moving back out of here for my truck survival [ from MS with some rust ]
