An overdue update: I ended up buying the van! I sold the International which gave me money to buy the GMC and then some. (he sold it to me for $3k) Serviced the transmission, charged the AC and we took it on vacation Memorial Day weekend. Put around 1,500 miles on it and the more I ran it the better it ran. (I think the fuel injector cleaner I added to the fuel helped a lot.) She doesn't like mountain passes; at 200k the original mufflers finally let go and I replaced them this week. All ready for the next big trip. Averaged about 18mpg, I know I can do better on flatter ground. (I-68 across western MD is a mileage killer) I'm very happy so far. She is a clean piece, really babied.
