Air Conditioner BTU rating

[J-squared]

We have a 2017 27FB with 50-amp and factory-installed dual air conditioners (AC’s). I have the following questions regarding the AC’s:

(1) Are the both the AC’s rated at 15000 BTU units,

OR is one rated at 13500 BTU, and the other at 15000 BTU?

(2) IF it is one of each, is there a quick and easy way to identify the 15K and the 13.5K unit without going on the roof for visual inspection?

The documentation I have favors the second choice. However, I haven't found documentation as to which is which.

I look forward to hearing opinions from the Forum.
