Hot water heater question

I generally shut the hot water off when we leave the trailer in the morning to go fishing or sightseeing and then turn it back on when we get back so we'll have hot water to do dishes, etc. I then shut it off when we go to bed as I don't feel hot water serves a purpose when we are sleeping. It's not a matter of saving money, I just turn it off when it's not needed. We did a 3,800 trip last spring, always in campgrounds with electricity but never used the electric side of the water heater, just used the propane as I didn't really need the faster recovery time of using electric and gas at the same time. As said above, if you have to worry about the cost of propane versus electricity, you might be a bit over your pocketbook.
