We purchased a Arctic King portable AC from WalMart this year to supplement our cooling needs in the hot West Texas sun. It does great! We are able to access the fireplace plug which has a dedicated breaker, and vent it out a small window in the slideout. We had to fashion a piece of coroplast sign board to hold the AC exhaust in the smaller sized window, but it wasn’t too difficult. We chose to still only run 2 AC at a time — the living room and portable, or the living room and bedroom — just to make sure we don’t overdo it on Amp draw. Our unit says it draws 11 amps. We don’t have to run it for long — just a few hours in the heat of the day — around 3pm - 6pm.
