About the only thing that will trip a GFCI is an imbalance between the hot and neutral currents, which the GFCI interprets as a current leak to ground. If you happen to know anyone with a "megger" they could check your Vanagon's 120V wiring for insulation failures. Otherwise I'd borrow or buy one of those extension cords with a GFCI built in, and see if the van trips it. If so, try unplugging everything inside (including the fridge) to see if you can narrow it down. If your GFCI doesn't trip, maybe the outlet at the camp site was defective. I once tripped a GFCI at home with RF. I hit the transmit switch on a 25 watt transmitter and the lights went out. ;) _ _ __ _ _ _| | | | David M.
