If you have a 50 amp RV, spring for the 50 amp autoformer. You can still adapt it down to 30 amp. Trust me 50 amp service can suffer from low voltage on one or both legs also. Better to be safe than sorry. You might want to think about hard wiring it in that way if you get to a park that does not want you using the autoformer it is not sitting out in the open. Also less chance it will grow legs and take a walk.
I agree with this post on all points. I also have both a Progressive and a Huges.
