I love some of the suggestions......
pound on it, torch it, heat/chill it
Don't worry......the porcelain lining won't crack
Penetrating oil. Spray it/let it soak
Then tighten a bit to break bond then remove back/forth
since when are they putting porcelain linings in RV wh? I would think all the bouncing and jostling while rolling 10s of thousands of road miles would do more damage to any lining than heating the iron plug with a torch for a few minutes.
no lining in mine, just straight aluminum, I looked in that hole with a flashlight once.
