Congratulations on you new hobby........ Everyone has to have a hobby, RIGHT!!!. Might as well be a TrailManor.
Here's a suggestion for your A/C unit. I bought this 7,500BTU inverter A/C for our bedroom so that we don't have to run the central air while we are sleeping (kind dumb, in my mind).
I am amazed at how well this thing cools and it is a quite as the mini-splits. All we hear is a whisper light sound of whooshing air coming out of the air distributor. Can't hear the compressor at all.
I'm thinking of taking the roof A/C off our TraiManor and replacing it with one of this.
When I first turn it on in a warm room, it draws about 800W for the 1st 30 minutes or so. As the room cools, the wattage slowly drops (as the compressor slows) until about 300W, (I have a wall outlet watt meter).This type of compressor doesn't need that drastic surge of power that is a generator killer. This thing would easily run on a 1500W generator, I think.
