I know with mine and other project trucks I have had in the past, my biggest annoyance is holes drilled in body panels for off road lights and crap. fewer owners and less sitting time I think helps with rust for sure.Probably sat tail low for an extended period of time. It really is strange how these old trucks weather the years. Some better than others. I believe It really depends on how many different owners there has been. Fewer owners usually equals less damage or things that have been changed. Of course …….Left Coast vs Right Coastunfortunately does play a role….
