Not sure where you are located but in January 2022 I purchased a 1986 D150 2WD 6cyl in Connecticut with 72k miles and minimal rust on the body or frame with a very clean interior (1 tear in the upholstery of bench) for $3000 although the truck did not start/run/drive. If the truck is in working condition I would recommend $3000 as a good starting price depending on your area.
