Pretty much all of your necessities will run off 12 volt and/or propane including hot water, heater, refer and lights. A decent size battery bank with 2 or 4 golf cart batteries will let you run for a day or two with no additional power and then can be recharged by running a genny a couple of hours. You can add a portable solar kit to help recharge without a big install expense or just go with a genny. If you want to run your a/c or anything else that requires significant 110 power you will need to run the genny.
