Thank to all that stuck with me on this one. Didn't get to it all week, but yesterday I got to the bottom of it. Special thanks to enblethen. He got me back on the right road when he said :
"Start by checking input to GFCI receptacle. Voltage present to line side of GFCI receptacle, then disconnect load side conductors. Try resetting GFCI receptacle. If it resets, there is problems in the load side wiring. If it does not reset, bad GFCI receptacle."
I did just that and BINGO ! I took out the front TV and all outlets downstream from that GFCI are working. Must have been a short inside the TV from the power cord. I could have taken it to a RV tech like someone suggested. That would have cost me several hundred dollars, plus I wouldn't have recieved this free education. I understand a whole lot more about how this coach is wired.
Thanks again to enblethen.
