Not for me.
I've camped all up and down the east coast, east of the big muddy, during the heat of the summer. And, all across the upper half of the USA too. The 13,500 BTU AC unit does fine in the 25'. I've been in 90+ degrees out in the sun and 100+ degrees in the shade without any problems. Interior temperatures in my 25' stay in the mid to upper 70's (my comfort zone), or cooler.
I have not experienced heat of the southwest USA during summer. Maybe, if I camped there in mid summer I would think about the second AC. I've never experienced that kind of heat and don't plan to.
Downsides of 50 amp service:
Two AC units running at the same time = LOUD
That 50 amp cord is stiff and heavy.
I would not want to give up one of the fans.
With the heavier cord and extra AC unit, there is a loss of at least ~100 lbs of payload capacity.
Downside of 30 amp service:
Can't start the single AC while running microwave/convection and converter at the same time. During hot weather the draw on the 30 amp cord will heat & sometimes melt the cord end and/or trip the main breaker.
