Depending on your situation there are also auto start systems which can be programmed to start the engine and allow it to run for a preset amount of time IE: start every four hours and run for 20 minutes then shut down and repeat every four hours or whatever you set it at. A buddy of mine has one on his Duramax and uses it when we go ice fishing and sledding. Works very well. I take my generator and use it to run my block heater when needed.
