Nec suggests 80% for continuous loads. 13.1 is more than that on a 15 amp circuit--and 14.2 is really pushing the envelope. I'm sure you know that voltage drop is bad for the motors in an air conditioner.
BTW my 13500 Dometic draws up to 1900 watts when it is hot outside. (actual watt meter measurement, real time) Even at 120 volts that is 15.83 amps. If it were a 15000 it might draw 17.59 amps--and that would trip a 15 amp breaker in short order.
No wonder the RV parks have problems with low voltage.
I fix low voltage with an autoformer. It makes my life easier.

I'd go for 13500 as they can be run on a 15 amp circuit.
A 13.5 Brisk air pulls 13.1 amps at 95 degrees.
A 15k Brisk air pulls 14.2 amps at 95 degrees
So, why can't you run either on a 15 amp circuit????????????? Doug
