If not for this forum I would have had a really frustrating weekend.
Hooking the trailer up for the first time, get it set up, turn on the fridge and electric hot water heater. Nothing. Check the circuit breakers and fuses. OK there. Hmmm, what could it be?
Seems to me I recall reading to check the GFI if there is a problem. Walk over, see the GFI above the sink is tripped. Reset. Turn on the fridge and hot water heater and voila, success.
This forum is truly a valuable resource and I learn a lot just by reading the posts. Better yet, the advice given has proven to be good common sense.
Thank you all
