We stay in FL and SC quite often. The 13.5K unit does well for us in a 21’ box. Most of the time it is only run at night.

A 15,000 is only 10% more cooling, but sometimes 10% helps. A little more airflow too.

One advantage, it will do the initial cool down quicker.

our previous TT was a 33ft 13.5 btu. it worked fine in the southeast summers... it took awhile to cool down when temps get in 90's but i learned to open bathroom vent and open rear window on the road to circulate air. that helped some. current TT is 37ft with 1 15k btu.

We had a 13.5 in a 32ft trailer and it was always good except in the direct sun. I would think you’ll be ok with your 22 footer!

I think you will be fine once it cools down, but getting it cool could take a while, especially in the hot and humid south.

I also think the 13.5K BTU unit will work, but if I had the option of 15K, I'd be all over it.

I had a 23.5 x 7.5ft trailer with 13.5 non-ducted and it was okay but noisy. I don't know how the models you have to choose from would compare in noise. However the most important factor may be whether you have a generator that could run one but not the other.

The 13 may work but you will be happier with the 15.

It should work out fine assuming it's a quality AC that is functioning properly.
