13.5 AC versus 15.0 K AC

[TomG2]

Dealer has two travel trailers that are exactly the same except for the air conditioner units. Any disadvantage to the 15.0 k models? Early freezup etc.? Either will be adequate for the trailer as it will be parked under a carport. I have a similar model with the 13.5 unit and it does very well. The 15.0 k model is the same price, so the only question is about efficiency and potential problems.

13500 has a better chance of working on a 15 amp-shore power. It is only slightly over 80% of the continuous rating on such an outlet.

I got a 15k on my latest TT and it rocks. (Never had it freeze up either)
For the modest extra power it draws (about 1A) It would be a no brainer for us!
