I think you have the makings of a great project. I think you will be surprised how strong and durable these old trucks are. There is much to learn and everyone here seems to want to help. That is the best part(driving the truck is really) of being a member of the stovbolt site.
Most fire trucks are normally kept inside for the majority of thier lives so they are normally in good shape to begin with. Our was only left outside for about four years before I found it in North Carolina and brought it home to be restored. It was pink and weathered on the right side from sitting in the sun and weather beside the building for several years. But it could have set for 20 years or more so, I figure we were just lucky somebody cared about that old truck.
anyway, pictures help alot!!!
