running ac or micro unit on tt while parked at home ??

If your going to keep your rv at your house on a permenant basis, just do it the right way one time and be done with it. Have an electrician run a dedicated 30 amp line to a new outside outlet. Your home breaker box should have several unused breaker punchouts. Just run a 30 amp breaker with a new line. Weather proof outside outlet, and now you can run anything, includung ac.
You will spend less on the materials to do it right than you will on a good quality 10 guage 50 foot extension cord.
