Yes I screwed up...With the sudden change of weather and cold temperatures I winterized the RV in a hurry and didn't check everything out. I did drain all the lines, tanks (water, black, greys, and water heater). But what I forget to do is check that all accessories where OFF before plugging back in the RV to 120 VAC power again so there the water heater sat running empty for over 24 hours and lucky enough nothing got hot enough to cause a fire nor did it seem to burn out the element. It was still warm to the touch on the tank. So I'll assume the water heater is not damaged for now and find out in the spring of the year. When your done winterizing make sure everything is turned OFF.
