Anyone on here have experience with replacing there gas/propane heater or just the fan on an older camper?  My daughter just bought a 1998 camper that has a super loud heater fan, the circuit board seems to work just fine, but sounds like the fan is going to fall apart.  Not squealing, just clunky.  Fans are cheap, whole new heater is around 400.  Anyone just replace their fan? Easy, pain??    Also, it came with an instant hot water source, they want to be able to have hot water dry camping.  Is it worth keeping the insta hot and using a generator ( will a 2,000 watt run insta hot?? ) , or would it be better to just install a 6 gal hot water gas/power tank???
