Check your undercarriage now and then.

there are no dirt roads in maine until you get up into paper country.. they'd be impassable for 3 months out of the year.

Not every vehicle is exposed to the same conditions. There are too many varibles to make a direct comparision on corrosion durability. I have a friend who has an '87 Chev Suburban. He bought a '90 Suburban for parts, that was WAY more rusted than his. Both trucks were winter driven and both were used in the same area, on the same roads. The '87 is still relatively rust free, and the '90 is a rolling pile of rust. I have seen this with several other vehicles as well.

That said, those of us in the rust belt that keep their cars for any length of time know that oil spray rust proofing is the key to long rust free chassis. It is dirty, but it works wonderfully.

Was one garaged and one left outdoors during the winter?

No, both were always parked outside. In fact, the '87 spent it's first few years as a RCMP K-9 truck, then my friend purchased it from the RCMP. However, I know that my friend would have kept on top of paint touch ups and kept it regularly washed, whereas the owner of the '90 didn't do anything to look after the body.

I wonder how that Rhino Liner pickup bed stuff would work under the car?

Another mechanism for rust is dirt caked to the undercarriage holds water.
