Fuel system flush, perhaps their term for cleaning the injectors, which is not a bad thing to do from time to time, but I typically don't bother with it. I run a bottke6 of chevron techron through every so often and that keeps things good for me.
Tranny fluid and filter every 30k, along with both diffs and the transfer case, regardless of what the manual says. Coolant is very important. Antifreeze looses it's anti-corrosive properties over time. I usually do mine every 3-5yrs, regardless of mileage. This is just what i do. I'm more perticular than most with my equipment
