One good or bad thing depending on your view point, MHSRV orders all of their coaches with max AC due to Texas heat. If a coach offers dual AC that's how they order, if only one AC they will get the 15,000 unit. One trip we were parked in the open sun with temp around 90-95, took both ACs to keep cool. Better to have to much than not enough when it comes to keeping cool.
Dual ACs are of course more expensive, generator is upsized to handle the extra load, again more expensive. You get what you pay for and if you want to stay cool it's gonna cost!
