Well we camp in it. No need for sink ,we wash the few dishes we need to in a wash tub outside. We don't boondock, so all the campgrounds (mostly state parks) have showers,toilets,and water. Yes it's an electric fireplace, heats the camper very well. We are not ones to park our camper and then stay inside it all trip. We are to busy outside exploring and enjoying the outdoors. No need for a oven or microwave we cook over the fire or on the Blackstone. Does have heat and a/c to make for a more comfortable night's sleep.
