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

Just wondering, those of you that turn your water heaters off, and on only when in use, do you turn your water heater off at home when you go camping?

For us, if it's a week-end or even a 4 day camp, we leave the water heater on at home. If it's longer, we turn it off. We actually have 2 water heaters in our house, both are 30 gallon and set to 160 degrees. (hot yes and both electric). I also flip the water pump breaker in the house to off. We're on a well.
