I have a new (just got it) 2018 Winnebago Minnie Drop 1780 with dealer installed tank heaters. The tanks are exposed on the bottom of the trailer. It was 20 deg F this morning and I turned on each tank heater and after 30 minutes of waiting I noticed absolutely no warmth on the heating pads. Could they still be working with no detectable warmth?
