Maybe they don't rate BTUs the way they used to, but the 11,000 BTU Armstrong in my 26' Airstream keeps the place cool in high-ninety, Florida temperatures.
I'm glad I don't have more BTUs because, when the outside temperature is only in the high seventies, the AC cycles a lot making the interior go from one extreme to the other. This is particularly noticable at night after the bedcovers are adjusted.
I advise caution. Yes, more BTUs might be appreciated in inordinately high temps, but for general cooling you might tire of the interior cycling between "a bit warm" and "put a coat on".
