I am a new motorhome owner and am having an incredibly frustrating issue. I was plugged in at a camp ground and, after turning on a microwave, lost all power. I have tested and am getting power from the extension cord, but nothing will turn on. I am guessing that its a breaker or fuse, but I can't find the fuse box anywhere! Does anyone know where I should look? I have a 1990 dolphin toyota.
