PS To answer you question, yes it would affect those appliances.
Once again, I'll carry our your suggestion. However, the heater worked the first 2 weeks of my (5 week) trip. The hot water heater went out a couple days before I started back home. Regarding the hot water heater: The pilot light
won't stay lit; it goes out after 5 - 10 minutes. The heater doesn't work at all: no blower when switched on. A new heater was installed (incorrectly) just before I bought the trailer, but the thermostat is rather old. I'm hoping the problem lies with the thermostat and not the heater.
