As someone stated, lighting this unknown vapor inside your trailer is not a good thing.
I always pull the pressure relief valve on the tank to fill it and then I know for sure it is full before turning it on.
Never heard of this before but sure is interesting.
This is incorrect, never open the T&P valve to fill, doing so will eliminate the air pocket that you want. The water pump will short cycle if there is no air and the valve may drip as there is no room for expansion.
I have always opened my pressure valve to expedite the fill of the water heater. If I don't it will spit until all the air is eliminated in the hot water tank. My cold water enters at the bottom, and the hot water exits at the top. So there is no chance for an air pocket anyway you look at it. It eliminates it by its self, if I don't help it out.
You can do it your way, this is my way.
