Thanks for your reply the is the answer to your inquiry
1) 12.9-13.1 while generator is running
2) Norcold 1200X IMXX set in the automatic mode.
3) Centennial GC2200P Deep Cycle, 20 HR Amp rating of 216
4) Magnum Energy MM-RC
5) Yes I have a small hand held volt meter tester
Perhaps the refer should be in the LP mode as far as a heater on the refer I am not aware of that. Not sure why there is a need for that either but I'm learning.
Also, as for the furnace yes it was running but not much as it was set at 60 degrees so it was cycling on and off sporadically throughout the night.
