Now, be aware that before you leave an RV park and you're using the electric side of the water heater...make sure you turn the switch off.
And...in the Spring and even during the RV season, always make sure the water heater is full of water before switching it on to use the electric heating element.
Or like me...you'll burn up an electric element. Fortunately they aren't expensive I paid $18 via Amazon. Here is a link to the correct element:
