Update. Well, got to Florida and brought truck in for assessment to my repair guy. Will end up spending about $3500 for a couple of leaks (differential, rods), tune-up, hoses, tires, coolant/tranny etc. flushes, oil change and a few other things. I did this cause: 1 - I am cheap 2 - I like the truck, it still sounds and runs great 3 - Repair guy (that I trust), said if it was his, he would do the maintenance and 'run the s#$t out of it'. So, my decision has now been put off for a year. (Or, unless I see an incredible 'on the lot' deal that calls my name.) The suggestions here have been saved and filed for future reference. Thanks to all.
