JohnD, Are you saying that the H/W heater in your TT only ran on LP/Gas? My 2012 North Trail had gas or electric or both. My 2011 Edge also had both gas and electric. I don't recall owning any RV that did not have both. Even my German Caravan I had in Germany had both (electric was 230V).
On edit. Never mind! I was reading hot water heater, but thinking refrigerator. It is all coming back now, laying on the floor, changing out thermo-couplers, trying to get the thing to light. Our NT and Edge did have both, but the previous ones only had a gas H/W heater. Sorry for the mixup.
