Close motor generator door securely.
Open fuel filler door (below driver window); add gasoline as required after setting instrument panel fuel switch on "main" (fuel capacity is 50 gallons; motor generator supplies itself by drawing fuel from main tank).
Close fuel filler door securely.
Check freon levels and working condition of the Heater/AC.
During fuel stops, routinely check underhood automotive components...engine oil, Coolant level, washer fluid, master cylinder brake fluid level, transmission fluids, radiator water levels and batteries. Do visual checks for loose or frayed cables, belts, missing or loose screws/bolts.

Check electrical compartment in wardrobe to see that the two circuit breaker switches are on, electric hot water heater switch is off.
See if there are spare fuses for living area fuse block.
Use monitor panel to check living area systems. First gauge indicates LPG supply remaining. Second indicates living area battery voltage (if below 11, needs recharging. Recharges automatically when vehicle is driven, when motor generator is run or when exterior power cord is plugged in). Third gauge indicates water remaining in supply tank. Fourth gauge shows status of holding tank (always dump tank before gauge reads full).
If there is water in supply tank, switch on water pump by sink; run water through kitchen and bathroom taps.

To run roof air conditioner while traveling, you must also run motor generator. Motor generator turns on with switch near refrigerator. If motor generator does not turn on, push circuit breaker on motor generator and try again.
Set both power level system controls to "travel" (if equipped).
Fuel pump switch should be pushed toward "main" (both tanks are connected, but when main goes dry, 7 to 9 gallons should remain in your auxiliary tank).
