I would do normal car things like oil and air filter. Path1 already mentioned addressing model specific maintenance interval items like belts, other fluids (tranny, differential, brake, power steering, coolant)and any other vehicle wear items.
Then I would go through the following laundry list.
Load test batteries and replace if necessary
Change out tires more than 7 years old
Pressure test the coach and address ALL LEAKS IMMEDIATELY!!!!!!!!
The real killer of any class C is leaking at the roof or the windows. If you stay on top of that, everything else seems to wear quite well.
