I own a forest river stealth toy hauler. Went camping in the desert over Thanksgiving weekend and had power issues my last night. I lost all power to my trailer. Checked batteries with volt meter and they were fully charged, checked 30 amp fuse in line with batteries and it was good, checked kill switch and it appeared to be good. No visible burned fuses or popped circuit breakers. When I operated the generator I had full power to trailer. Once I turned off generator all power was to trailer. Any ideas?
