For starters, I'm surprised know one has mentioned needing a good sized battery bank. I would start with 4- 6 volts. If you do not need air, get a Honda 2000 (3000 if you need air) and you should only have to run it maybe 2-3 hours a day if that to keep the batteries charged up. Run the fridge and water heater (only when necessary) on propane. We can boondock several weeks at a time on one 30lb lp tank and 5 gallons of gas.

Do not use the on board genny ( as you found out they really suck up propane) and keep a watchful eye on the 12 volt things you use like lights. Do not leave anything on that is not necessary. Use a propane grill for most of your cooking needs.
