We have propane lights and stove but now that 3 of the 5 guys in camp sleep with CPap machines ( we now call it Camp Apnea) we actually run a Honda 3500 genny all night now. It powers all the lights, toasters and coffee makers effortlessly. We probably burn less than 10 gallons of gas in a week. We rarely use the propane light system any more, just the cooking stove. We top the genny around 9:00 pm and it runs straight through the night no problem.
