The joys of living in the rust belt.
Sold a 1992 F250 a few years back. The old 7.3 just rumbled along closing in on 300k miles but the rest of the truck was rusting away. Sold it to circus folk (yes, literally) and they were headed out the next day across country.
I know truck prices are crazy right now but you may want to look into if it makes sense to dump a couple grand into a truck that may only be worth a few thousand or if it's time to sell and get something a little newer (hopefully not from a rust belt state)
