Well it's 45-95 amps for 9000 BTU, so I think that you would only want to use it on the ground, with an external power plug. In Louisiana where I fly often, this would not be very practical - because even if I do totally cool down the interior, I'd have to unplug it, open the tip-up, climb in and such. Any cooling that I might have enjoyed will be gone in boarding. Then taxi time - a hot process with canopy cracked. The plane's alternator can't drive this unit. I suppose you could wire your backup alternator for it, but that wouldn't work well because of low taxi RPM. Even on the hottest days once airborne things cool considerably and are quite comfortable so it's a ground problem for which this isn't a very good solution for an RV.
Alternatively, I suppose one could add a battery that when isolated would supply just the AC for a time; recharge in flight with AC off. Obviously this would be time limited. To recharge a deeply discharged battery in flight should require a charging system so a big discharged battery doesn't suddenly show up on the ship DC bus when you throw a switch to charge it. I suppose a simple contactor to put the battery on the bus for charging could work in some situations but I'd prefer at least a high-power current limiter. A battery could be mounted in the baggage area, and the weight of battery and AC deducted from baggage capacity.
Then there is the installation itself - intake and exhaust paths.
