Here's how I'd approach it:
1. Check the battery and recharge/replace as needed.
2. Top off any automotive fluids before starting.
3. Air up and inspect the tires.
4. Take it to a reputable place and have oil, filter, trans fluid, trans filter, fuel filter, brake fluid and power steering fluid changed. Condensation over time can contaminate these fluids.
5. Drain, fill, sanitize, drain and fill the fresh water tank and system.
6. Go to an RV park or other place with full hook ups and check out all the RV systems just as you would during a predelivery inspection. Pay close inspection to the roof, including all caulking and seals around vents and other roof penetrations.
Once everything checks out, hit the road and enjoy.
