I turn mine on when I get there and shut it off when I leave.Most places I camp, the elec. is included in the daily fee so I dont worry about using up the kws.
I do turn the gas on after the electric has heated it up.The gas only kicks on when we start using alot of water and helps recover the temp faster.
But this year with way the price of propane has gone up, I may rethink that operation and just run the electric.
