13.5K BTU AC versus 15K BTU AC
So we were not forward thinking enough when we purchased our TT back in December and opted for the smaller 13.5K AC in lieu of the 15K BTU option. My thinking at the time was that the smaller unit ha...

It's tough to compare since no one here has had each size a/c on the same trailer.
FWIW, my last trailer had a 13.5 and my current one has a 15. Same size trailers but I don't know if the insulation R value is significantly different. In any event, the new one can definitely hold a larger temperature differential by 3-5 degrees and the a/c cycles less than the prior unit. No way of knowing how much of that difference is attributable to the a/c. Probably some, but 15k is not that much bigger than 13.5k.
For me, it was a no brainer to upgrade for $150 at the time of purchase. But I don't think the difference enough to justify a significant sum...I think you'd get much more bang for the buck adding a second 13.5 unit.
