2nd AC size

We have a 37' travel trailer. For travel trailers and 5th wheels in the 35-40' range, I am curious if most of the second AC units (Bedroom units) are 13.5k or if people opt for the larger 15k. We are pre-wired and looking to add the second soon. Considering we have been living with the single for 4 seasons I suspect the 13.5k will be plenty and possibly a tad quieter, but I'd like to hear from those who have added it and which way you went. Thanks!

    Seems to me for the difference in price, why not have more than what you might need. You can always run it on low fan. Living in So. Cal it would be a no brainer for me but on the east coast?? Maybe/maybe not!
    I guess I'd still say " to big"....

    Both our prior 40 ft. 5th wheel and our current 27 ft. TT have/had dual ACs. In both, the front or bedroom AC is/was 13.5k. If you're having it added, you could go with 15k but probably overkill for the space. Quieter? Because the space is smaller and it is right over your head, I would say not really.
