We have a 2015 and love it!!!!! Ours has one AC and it dose a great job at cooling it down and maintain it. Last June we traveled all day 8 hrs in 98-102 temps when we got to our site it took about 20 min to cool it down to 68 degrees and had no problem keeping it there. As in over all we have had no real problems a few little fix's in the beginning. From May 2015 to current day we have just under 8000 miles and 45 nights, It still feels brand-new.
