The above numbers I mentioned would be less if I use the heater, stove, and generator. I drive my camper mostly everyday to work and seldom use the heater, stove or generator. That's the beauty of living here in southern California, winter doesn't get that cold and not so hot during summer
We have camped about 18 nights(all but 2 dry)since our last fill and still haven't gone through one of our 30lb tanks. It runs the fridge, stove, oven, water heater and heater. We do keep our heat low (between 55 and 60) and only run the HWH sporadically, when we know we will need it. But we do heat a lot of water for coffee!
