Is there any thing other than the usual I should check on a 350,000 mile truck before I'm east bound and down?
BTW I'm goin to Peru IN then down to Louisville KY then up through ST Louis MO and home from there.

The usual consists of
1. Fresh oil change
2. Change or top off lube in the tranny, t-case and diffs
3. Valves have been set
4. Wheel bearings were inspected and packed in early December
5. Brakes all look good
6. Turn the fuel down a smidge for mileage[duhhh]
I will have tools, a spare belt and tensioner and fuel filter, an assortment of jumper wires, oils, coolant, and a multi meter a carton of smokes, duct tape, and bailing wire.
Feel free to add as you see fit
