Electrical Problem

Thanks lanerd for the inverter suggestion, makes sense. I'm still quite new to the RV scene. For the other folks who weighed in, thanks. I have rehab'd 4 houses in the past and have some knowledge of electrical systems. The first thing I did before buying a new GFI was to "push the reset button" several times. Also, as previously mentioned I couldn't find any other GFI's inside or outside. Tested each outlet with a circuit tester as well. So the most logical course before hiring a RV electrician is to try the inverter reset suggestion. Thanks to you all. I'll let you all know what happens.
