AS Howard - @Hoppy Frood states should not hurt a thing. My last two trailers were always plugged in. Never had an issue. One suggestion though. You said you have a 50a plug in at home. I would get (maybe you did) a 30a cord and a 50a to 30a dogbone adapter and plug in that way while at home. The 30a cord is MUCH lighter, and unless you are going to run 2 AC's while at home, will work just fine.
