Well really if you only have 30 amp there isn't much of a checklist:
- Make sure the waste tanks are pretty empty (you'll still want about a gallon or two in the black tank with some deodorizer or enzyme treatment but the grey can be dry)
- Fill fresh tank
- Plug in
You'll want to keep an eye on the tank gauges while you're there--although with a unit that old the gauges may not be functioning properly. That really is your biggest challenge: Accurately determining how much fresh water you have and how full the tanks are. Especially if you're staying a full week. For a week I don't think I'd plan on bathing too often in the coach; if you do you'll want to take extreme Navy showers!
Aside from that: You'll have power so you can use all the appliances; including the A/C.
