To OP, For your size TT, 13.5K will work fine.
Our Jayco 23RB is 23.3' long box, (280"), or 187 sq ft, and the 13.5k A/C cools it just fine. I don't know if being ducted forward to the bed area, to the bathroom in the rear, or the living/galley area in the middle helps with the overall cooling or not.
If I were ordering one brand new, I'd go ahead and opt for the 15k unit, since that option at Jayco was only about $150 more and a little more never hurts.
