John, about the only comment I can make is Airstream daisy chained a lot of the circuits. My best guess is one of your connections is bad. I'm assuming your connections were with yellow or red twist wire nuts. I would suggest carefully looking at each one of those connections closely and giving each of the wires a good tug to see if they might be loose. I've also seen where when twisting the nut on one of the wires will break off and even though it looks to be connected it's not due to the break.
