We have a Winnie Vista with bath and 1/2 and two AC's - frequently camp for 1-2 months in Florida and take lots of short trips around SE from SC to TX to see grandson race.....definition - lots of AC camping for us.
Other than the first couple of nights we were in our Vista, we don't hear the AC turn off and on - -sort of like in our house - get used to the on an off sequence.
We find the AC works very well - if we are in direct sunlight for afternoon sun or no shade at all - we will leave the front curtains closed and the screen shades down in other windows -also if sun is on side of unit where awning can be out (minus strong wind) we keep it out as it really cuts down on the heat - stays pretty cool unless in days and days of 100 plus weather - then you can easily keep it at around 80 but not much below.....when it is 100 plus outside - 80 degrees is very good! Of course, even on hot days when the sun starts to set the AC works less.
Happy Trails to you!
