13500/1500 air conditioner?

My 13.5 works flawlessly in all conditions including the mid 90’s and above into the 3 digit heat… if most of my camping was in those high temps I would get the 15… but I can say with confidence to big is not better or more comfortable than to small…
In my 20 trailer the 13.5 was very uncomfortable… it was like sitting in a wind tunnel and cooled the temps very quickly, to quickly… but wouldn’t run long enough to remove the humidity… the cool camper with the high humidity was never comfortable and the cooler you made it the worse it got…

I can't speak for everybody else, but I can speak of us. Ours is a 13.5 and it kept up acceptably in Vegas at 100+ temps. It may have something to do with level of insulation rather than just plain size of unit. It got up to almost 120 during the day and we never had truly "cold" water, just from the hose exposed to the heat. Even if you let it run and run, it was still warm. But, the AC seemed to keep us comfortable in spite of the ambient temps. We've been in 100 degree + , and humid here at home, and I have no complaints so far.

We have a 29' Rockwood and the 15K a/c does NOT keep up in the summer in the SW desert after a day of driving. A 13.5 would be out of the question for us. We are looking at a Roamer for our next TT sometime next year; one of the selling points is improved ventilation coupled with 50 amp service and prewired for a second a/c. I guess it really boils down (so to speak) to where you plan to go in the summer.

Go with the 15K. Some of the newer units are******and may not even be cooling as much as there advertised. Get the bigger one right away.

Hi

15000/13500 =~ 11% larger.

I you really want "more cool" add a 2nd unit.

I would suggest the same, but most likely a 30' TT only has 30 amp service and that will not run 2 units.

I agree. One often overlooked option is the high efficiency 13.5 K units that Coleman and Dometic offer. These units draw 4 A less than a standard 13.5 K unit. Coleman claims their Power Saver has greater cooling capacity than their standard unit. You could actually run two high efficiency 13.5 units for about 22 A.

Go for the 15,000. My 35' trailer has a 15,000 and sometimes it just barely keeps up.

Hi,

Simply run a 2nd auxiliary shore power cord for only the 2nd air conditioner--or add a 7000 btu unit--which would run just fine on 30 amps with a 13500.

The nice thing is the cord can be used for extra heaters in the winter time.

Another vote for the 15K BTU AC unit on a 30 footer.

If you have a lot of windows, the solar effect works well in a camper...

I have a 28 ft tt with a big slide and the 13,500 on mine is sufficient and the warmest weather i have been in was Vegas at 111. I could see it not cutting it where the humidity is high which is where most of the responses have been from. If your staying in the west i think you will be fine.

Yes get a 15k BTU
