Check you manual or Workshop CD for the stuff they are missing that are pretty critical - diff drain and fill, TOD drain and fill, wheel bearing repack, and adjust valve clearance (if needed). Timing belt is listed at 100K (severe duty 75K), plugs at 100K. Tranny FILTER is a huge thing they are missing - even if you have had it flushed and filled, filter is sooooo important - call any tranny shop and they'll tell you to change it well before 60K. New tranny is only $3500....

$131 for spark plugs! Such a deal....NOT.
