I have three 15K ACs. In Phoenix AZ, I would not want any less cooling capacity.
What mini split setup would I need?
Pretty sure you are mocking me ( ;) ) but I've talked to a couple people that have mini-splits in an RV, my parents have one in a multi-room addition they added to their house and I've read and watched a bunch of videos on them. The mini-splits are vastly more efficient than the roof top AC units in RVs. They aren't trying to blow cold air through inefficient and hot ceiling vent systems, they use a moving fan head to blow air throughout a space.
If your camper is big enough, or if you close doors, you may find that 2 mini-splits would work wonders in your camper. Looking at the cost of adding a second rooftop AC to a trailer (about $1200 MSRP), you can buy a DIY mini-split for about half that price.
From what I've experienced and read, the mini-split cools the space MUCH more efficiently, much more quickly, much more inexpensively and much more quietly.
Or, if you are happy with your 3 rooftop AC units, fantastic for you. Personnally I know that I can cool (and heat... its a heat pump) better, for less money, be more comfortable, hold a steady temperature, get much better dehumidification and do it for less money (initially and in energy used throughout its life time) using a mini-split than using rooftop ACs and propane furnace.
