I would say 30K on the trans fluid, rear oil, fuel filter, on top of all the other usually items that come due every service. A typical 70k service should be the same as a 10k Service since all the major items should have just been done at the 60K mark.
I like to do my fuel filter every 15k, the timing belt every 60K, and all the gear oils every 30k. It may be a bit of overkill but it's cheaper to catch an possible problems early rather than wait for a break down. I check all fluids and change my oil every 3,000 to 3,500 miles. Brakes should be checked every 15K or so, and most are due for replacement around 50K with some trucks getting as much as 75K out of the rear brakes.
Antifreeze should be done every two years or roughly 60K. The same for rubber parts like belts and hoses.
