Okay. Please explain this? I really do not care where the cool/heat comes from. I like that there is only one engine running at a time. I have concerns about constantly running the generator, unless that really should not be a concern.
I assume the alternator is aftermarket and very robust? It charges the batteries and the batteries and inverter power a couple of the roof units?
The "alternator" he is talking abut is likely an 8000 watt version which is mounted to the engine and works much like a generator would as it provides plenty of power to run 1 or 2 inverters allowing the use of roof airs going down the road. They eat fuel as well as it can take as much as 50 HP from the engine to operate this beast.
To your comment about running your generator, you really should not be concerned. It will work fine and there are no issues with running while driving or parked other than it burns some additional fuel. If your dash air is working properly you should be able to keep the drivers cab area cool unless you are in very hot weather. When you get where you are going your coach air will cool the rest of the coach pretty rapidly. In most cases, there is no reason to keep the entire coach cool while driving.
