If you haven't yet bought a small fan for your sleeper, now is a good time to do so.
We have a roof vent fan in our sleeper and we use it but we also have a small desk fan that makes a huge difference this time of year. It oscillates so even with the a/c on the air continues to move. That means we can keep the a/c temp a little higher so the generator isn't constantly coming on. These little fans are not expensive and there are times that the fan plus the windows open in the sleeper make it just right.
