Hi All!! My family are getting back into the RV scene after getting away for a few years. We purchased a 2022 Cruiser Aire 28RKS. This is a 32'-9" trailer with one slide that runs the length of the Ki...

I added a second AC (13.5k) to my 35' 5er. Living in TX and most of my travels in the south/southwest means long travel days in 100 degrees are common. And the trailer would be quite warm after 6-8 hours on the road. The second AC greatly improved the cool down time after setting up. But by bedtime we would shut off the second AC and rarely start it back up on subsequent days at the same location even in very hot temps. Once the trailer was cooled the main 15k AC would keep it cool.
And I agree with comments above about which hot leg to connect the second AC to. Balancing is the key. And if the "other" leg already has several heavy loads (microwave, water heater, converter, kitchen outlets for coffee pot/toaster, etc) it may make more sense to put the new AC on the same leg as the other AC if that hot leg does not have much else on it. 50 amps on each leg is more than enough to run two ACs. And if you happen to have to connect to 30 amp it doesn't matter any way.
