Hot water heater... turn off & on??? gas or electric???

I leave the gas burner and the electric element on all the time. We never run out of hot water that way. If I'm at a site with a shortage of electricity I'll shut off the electric element. Other than that, it comes on when we leave the house and goes off when we get back home or stop for gasoline.

I don't care about the cost. When you spend 45K for tow vehicle, 30K for a trailer, $100 for a tank of gas why sweat a dimes worth of electricity or propane?
