That white 'nut' is actually a nylon drain plug, use a 1" socket to remove, then open the pressure relief valve and it will drain the water heater. Important have city water disconnected/turned off and water pump turned off as well as turning off the heater controls, gas and electric (if equipped). Also water temp should be cool.
Bypassing the heater for winterization is done on the inside of the RV, behind the heater. One or three valve system.

If you don't relieve the pressure, before removing the plug, you will have an unexpected shower. plus the plug comes out much easier.
