This morning I went out to clean the trailer and I have no power. We have a Progressive Industries surge protector/power monitor in it and it shows no error code and voltage coming in to it is good. ...
Well the problem is solved. I replaced the GFI outlet in the bathroom and we have AC power again. I realize that not all trailers are configured as ours, but if you lose power the GFI outlets are something to check. Needless to say, we will add a 20 amp GFI outlet to our stock of repair parts. We may never need it, but I don't want to go through this hassle again.
