Thanks for your comments and suggestions. I took the trailer to CW in Roanoke and they assigned Glenn, their top tech. I was concerned about losing food in the frig/freezer if I didn't get it back working ASAP.
Glenn found that when I put a 1/2" shim for my ProPride jacks, I had pinched and shorted out the umbilical cord. (The ProPride is designed to go on a 2 1/2" frame; I have a 2" frame and the jacks were rotating to about a 45 degree angle. I didn't see the cord when I reinstalled the "U" bolt around the frame.)
Glenn found that I had blown a 40 amp fuse block in a 4x4 electric box under the trailer. (all of the fuses and circuit breakers inside the TT were intact.) He taped, rerouted and repaired the cord and I was back in business. Total time about 1 hr 15 min.
For as many negatives I've heard about CW, the Roanoke facility, and in particular Glenn, were First Class.
