Refrigerator, lights, microwave, water heater all run on the
generator. Most manufacturers recommend oil changes every 100 hours. If
you do not know when the last time the oil was changed, do it before you
leave for a road trip. The process is simple and quick. Change the spark plug as well
if you do not know when it was last serviced.
Before you leave check the electrolyte levels in your inverter batteries as well.
Follow the instructions as to specific gravity and water levels (use
only distilled water with deep-cycle batteries). Of course, when working
with battery acid, always wear rubber gloves and eye protection.
