How to keep RV warm enough in winter to avoid winterizing

I live in the Pacific Northwest and I don't winterize! I set the inside heat in my Winnebago at 50* and turn the gas on in rare cases which the temps get below 32*. My coach has basement heat and I leave my hot water tank on also. My water tank is on full and I leave the water pump on to keep the water lines charged at all times. In rare cases where the temps get around 25* I turn my compartment lights on and open all inside cabinets.
