Ok, my final post in this topic. Everything has been resolved. As I posted earlier, our 50 amp power setup along with a hard wired SurgeGuard is 'unusual' and PC USA didn't install a jumper wire on the transfer switch. Kermit walked me through it and 5 mins later I had power.
The no-heat/thermostat issue was finally resolved. Again, this installation was non-standard....we opted for the Coleman Mach 8 15,500 BTU A/C with heat strip (not the heat pump model) Kermit and I talked about it for a while and it looked like either a miswired thermostat or a short somewhere. Due to how the the thermostat wiring runs in the PC, I couldn't find the problem myself so I brought it to one of our local RV dealers with a massive repair facility (Cordelia RV). They found the problem on the first day I brought it in (there was a short somewhere) but due to their backlog of service issues (they had about 60 RV's in there for one issue or another) they couldn't get to it for two weeks. Thankfully, these were the two weeks we experienced an abnormal two weeks of hard freeze in this area, so our PC was cozy and warm in a service bay, inside. Turns out the short was due to a wire nut coming loose, falling off and making contact with the control box in the rooftop a/c section. Not only did they not charge me, but also washed the rig nicely.
We now have a fully functional and gorgeous PC that is ready to get on the road. First stops....Red Bluff, Palm Desert, San Diego after Christmas. Then across the country once we get the Ford Edge tow gear and braking system hooked up.
Kudos to Kermit for keeping in touch and being extremely supportive! I'll post more about our 50 amp service, SurgeGuard and Coleman a/c in relevant topics.
