I have three ACs in my 2014 3850RL. None of them short cycle. I have the living room AC set on 74, kitchen AC set on 73, bedroom set on 73. As long as it's not over 100 outside, all works well. The cycle as you would expect. Once it gets over 100, they run quite a bit longer (nature of the beast since insulation is minimal).
The difference in temp between the living room and kitchen allows both to cycle. If I set them the same, the living room one runs quite a bit more than the kitchen. Trial and error showed I needed a 1 or 2 degree difference setting between the ACs and they work fine. The kitchen one helps the living room one do its job.
Bedroom is a smaller area (height wise) and cools off faster. Shorter cycle times seems to occur but maintains temps very well.
