Look for the largest capacity you can find. If you also use it for heating, consider getting one with a heat pump. Make sure your choice is compatible with the ducted installation. You may need to update the thermostat and wiring.

I replaced my older Dometic DuoTherms 13.5K BTU units with low profile Penguin II high capacity 15Kbtu units AC/HP.
I called PPL and talked to a rep, told him what I had and he told what I need to replace. The newer units required a thermostat change also, he recommended the 10 button CCC but I decide to replace with the MicroAir.
The main reason was that the MicroAir can be controlled by both Bluetooth and Wifi and you can program it to send alerts for a set temp. My wife travels with dogs and I thought this would be a good option. Paid off this last month, she's been in MI visiting friends and a couple weeks ago temps got to +95F and she only had a 30 amp service. Running 1 AC she was able to keep the coach at 76F. I could periodically check when I got alerts on the temps.
One thing I did before installing new AC was to buy a remote camera and checked my duct work. Glad I did as I found mouse holes on both ends plus one large one in the middle. Also found one of the duct joints not sealed. All those resulted in a pretty significant loss of conditioned air into the ceiling. I think the combination of up sizing the AC's to 15K BUT and fixing the leaks improved cooling capacity significantly.
