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 ar...

The only thing I would question over the "bigger is better" folks is, how do you camp? If you frequently dry camp, you may find that a supplemental 9k to 11k btuh unit may allow you to run a little 2000 watt genny to power the slightly smaller ac unit on those occasions you dont have a shore power tap available.
You aren't running 2 air/con units off a 2000 generator.
If you plan to run the air/con off grid, better to jump up to a 3000w generator.
No, I'm not suggesting running two AC units off of a 2000 watt genny, but you can run a single little 9000 btuh AC on the small genny, which is not normally doable with the 15000 unit.
Still better to jump up to a suitable generator (up around 3000w) but a 2000w can usually work if you use a soft start and make sure nothing else is running...but that applies even if you put in a small air/con. It's the startup load that is the challenge for undersized generators.
