Hello all - inheriting a truck - could use some tips

IMHO, do one of two things;
1. Sell it, take the money now.
2. If you are committed to keeping it for sentimental reasons. Properly service the truck for ‘long term storage’, ie; drain the fuel tanks, do a complete PM from top to bottom, properly ‘fog’ the cylinders, arranged for inside storage not just under a roof. Consult a competent mechanic that is well versed on long term storage of vehicles. Any short of this, just sell the truck.
