I then used electric for a 24 hour period to make sure it was working. Next, I turned off the electric around 6PM and, as others have told me in this forum, the water was still warm the following morning.
Many things will contribute to 'how long' you'll be able to go before it gets cold.
The inlet temperature of the water going into the tank is probably the biggest factor. If very cold well water is the supply, then it will take the tank much longer to recover from the cold shock than if the inlet water has been laying in a pipe just beneath the surface of the ground in a campground for hundreds of feet.
The other biggest factor is the GPM flow of your shower head.
More flow = more hot water used.
Enjoy your camping!
