I'm a big fan of doing services on much shorter intervals than the dealer/manual specifies. I've been burned by waiting the full interval on some of these 100k+ services in the past. Do some looking on transmission, rear end, transfer case (if you have one), and plugs in particular. Oil at 3k for normal and 5k for synthetics should be obvious at this point. 
Good luck!
