Not basing on experience, but you would also want to consider the power draw that the 15K over 13.5K would have on the shore power. I would just try to figure out what additional amperage it would have on your 50A hookup...probably negligible, but something worth considering.
The way they are normally wired 1 A/C unit will be on each leg so they each will have plenty of power.
We put a 15k non ducted heat-pump in our bed room. Works fine but a little hard to see and read the controls over the bed.
