Thanks everyone for their help. as it turned out, this was not a voltage issue entirely. I finally got an opportunity this weekend to get my multi-meter and properly check my circuits. Batter was good at 13.29 volts with coach unplugged and 13.56 volts when plugged in.
I went to the distribution panel and when to check the circuits and the last 12v fuse checked was actually marked for the slideout, I pulled the fuse (not blown) and replaced with yet another 30amp fuse, the air conditioner came on immediately and the other issue resolved. When I took my hands of the fuse, everything went back off. So, over time the female spade had slightly separated not allowing the fuse to make 100% contact. I tightened the terminals with my needle nose pliers and viola! All is right in the camper again.
