Air conditioner size
Will a 13.5 AC be enough for a 29ft trailer? Most temps under 100 but occasionally up to 105 thx

What makes the answer even more complicated is that one can have too LARGE an a/c because if it cools too fast it doesn't dry the air and you end up with cool clammy air! I vote for 13.5.
We also find an oscillating fan helpful to move the cool air around.
Given the poor insulation of all trailers, the 13.5 is inadequate in all but the smallest trailer. It's possible in theory to get the space so cold that the AC short cycles, but you are never going to see that in a trailer. More is always better and in Nevada, you are going to need every BTU of cooling that you can get, and no, it doesn't matter if it's "dry heat", it's still heat and has to be removed from the trailer for you to be comfortable.With the 15KBTU AC being about a $150 option, that's a no brainer, you'll be comfortable and it will help the resale value of the trailer.
I disagree. My 27 ft Bigfoot has excellent insulation and the 13.5 does awesome. Of course it is a true four season trailer with thermo pane windows, awnings for all windows, etc. BTW, I live in Phoenix where it is 115 degrees in the summer. And dry heat DOES matter! Removing the moisture from the air takes energy, which equals less cooling.
So it all depends on the TT setup.
Disagree if you like.. Your prerogative..
If you have a true 4 season trailer, congratulations. We are all happy for you. The brunt of production trailers, in spite of the ad hype about Polar and Arctic Packages, and inflated published insulation R values, are 3 season trailers at best, with poor insulation, single pane windows, and poorly installed plenums and duct work, and they need al the help they can get, even after fixing the manufacturers shortcomings. Also, my comment about it being unlikely that the AC is going to overcool and short cycle still stands. It's not going to happen on the average production trailer, and the $150 difference between the two units, assuming there is only going to be one, still makes it a good value.
