35 minutes seems like a long time to recover!You run out of hot water and in 35 minutes it's hot again On Gas.
If that water heater can be run on gas & electric at the same time it cuts reheat time. I have a 12 gallon suburban and last summer changed the thermostat from the stock 130 to a 140 big differance. (wife like long showers)35 minutes seems like a long time to recover!
I am glad my new RV cannot ever run out of hot water. It has the tankless option. I also like the way I can set the water temperature to exactly what I want.

Tank heater pads are fairly rare on the average trailer (or motorhome) and would be marked as such. I feel rather sure that the switch in the pic you are referring to is for the gas side of the water heater. The switch illuminates when it is switched on, the red light next to it illuminates if the gas fails to ignite properly (Atwoods try 3 times, I bet Suburbans do too), basically a fault light.Referring back to danford49’s pic, the heater light that is lit I assumed (yea, I know...) was the black and grey tank heaters (heating pads) not the gas/electric water heater. I have the outside switch that adds electric heating to the propane hot water tank. Correct me please!
