Hey everyone!
Doris is alive and kicking!!
We found the problem and got it fixed - hopefully I won’t get this wrong- the distribution J box had a meltdown - there was a short and it actually melted old wiring together. Brand new everything - I have the melted mess in my hand. We are so so lucky. It could have been way worse. I’m grateful for everyone’s help and advice here. We have had our first real life lesson in knowing as much about your RV as you can and always be willing to learn. Many thanks to everyone who contributed and taught us so much!!
You all are the salt of the earth!!!!
