Mini splits and full size buses

[diannetea]

I've been pondering mini splits for a little while, and I'm mostly wondering how well a single 12k btu does in a full size bus (~40 ft). My guess is the biggest problem with a single unit is that the air pools in the area where the split is located leaving the rest of the bus hot/cold, so I am wondering if perhaps this could be solved by making some sort of air duct with duct fans to pull the air to the opposite side of the bus.

So, full sized buses with mini splits, how does a single unit fare? How feasible is a duct system to move air instead of installing two mini splits? If two splits are really necessary, what size generator would be needed to run them?

Depends a lot on your insulation, but 2 units minimum of unless you are in a mild climate.
