New Ducted Air Conditioning

I am considering buying a new 2015, 28 foot with directional ducted air. I looked at one with the ducting and it looks beautiful and sounds better than current method to disperse cold air.
My concern is that a lot of cold will be lost in the distribution system and the result will be inadequate cooling with current BTU recommendations.
I was in Texas last week at 99F in a sunny park spot and the 15,000BTU system on my 25 Flying Cloud just did not cool well. If I was to lose any cooling from current system it would be really bad inside on a sunny day.

Has anyone with a ducted A/C experienced poor A/C performance?
Thanks.

I think you have answered your own question. If the 25' trailer with the 15K air conditioner was marginal in Texas, and assuming it is functioning properly, you can't expect a larger trailer to be adequate for you with the same BTU rating. Ducting won't help you make that air colder and if it creates any additional back pressure into the air flow, that loss will make a marginal situation all the worse. Running air through ducting creates friction and because of the ducts and outlet vents, its inevitable that you will get a some loss of efficiency. How much depends upon how well Airstream sized the ductwork and how many curves that ductwork has in it. Air resistance from the vents themselves can affect outflow.

Dual air conditioners on a 28. On my 2015 Classic running one unit is good into the 80's. pass 90 and better to run both. At 120 in Las Vegas or Phoenix with no shade not sure anything will keep up other than being in a casino
