I have received conflicting instructions from THOR.....

I have a 2018 Challenger 37TB with blue and red low point water drain valves. I opened both of them along with the fresh water tank drain. Then my husband (after a significant struggle) removed the water heater drain plug. When no water drained out of the water heater, I called Thor back and was told that it was unnecessary to remove the heater drain plug, as it had already drained out when I opened the other valves.

Is this accurate? The first Thor tech told me to do both. Do I need to fight with the drain plug when I winterize or not?

Appreciate the advice of other Challenger owners!
