In regards to the best AC for RV cooling, the number represents how much heat is being removed from the air. It’s a battle between yin and yang.

What Size Air Conditioner Do I Need For My RV?

A simple answer is, If you are driving a 32 foot RV then you will only need one average-sized portable AC.

It can get a bit more complicated, this is where you have to start assessing your square footage needs.

How Many Square Feet Can a 13500 BTU Air Conditioner Cool?

Also, it would be best if you considered amps.
