We are considering a Flagstaff Micro Lite 21ds. The standard AC is 13,000 btu? Is that adequate or should we upgrade to the 15,000 unit?

Thanks,
Dennis

How cold do you need it to be? I know you are in KY and I'm in WA, but I have been in 100+ heat and the AC will keep my trailer in my sig to whatever temp I want to keep it at, which is around 75, because any cooler just gets cold with the fan blowing on your body anyway.. I could get it to 68 if I wanted, but that's just too cold when it's 100 outside..

We don't have the humidity that you probably have either, so I guess I'm just talking out of my ass.... [emoticon]

If you have the option to get the 15k unit, just get it and adjust the temp as you please.. That's what I do with my 13k unit (that is over 16 years old now) and I have never had to turn the temp dial to max and the fan over LOW ever..

Good luck!

This is an easy one. How happy are you when your hotter than you wanna be? If you tolerate the heat well (along with all those that camp with you), save the money and use it for trips.

If Being hotter than you wanna be gets you cranky or ticks Momma off, You better write that check and get the 15K version pronto!

As always, It's better to Have it and not need it than to not have it and Need it!

For a 22' trailer, 13k should be fine. Not a bad thing if the 15k is a cheap upgrade but certainly not critical.

The 13,000 is fine for that length, but if your trailer has a 50 amp service, (which I doubt), I would do it in a heart beat.

If your trailer only has a 30 amp service, don't do it. It could prevent you from running other electrical appliances at the same time it is running

I have a 13 in my 2002 26' 5th wheel. Works just fine.

I don't know if it is like a home unit in the fact if you go to large it doesn't run enough to take the humidity out of the air.

My 13,500 works well in my 35' seasonal up North by the Canadian border. If the same trailer was parked in the Southern US I would probably want two 13,500 units for that size trailer.

If the 22' trailer is insulated a 13,500 should do the job.

Thanks for the replies. Our last unit was a 36' trailer with dual AC units and 50 amp service. On really hot days we would use both units for the hottest part of the day. We do like to keep it cool, especially to sleep. I was hoping that a 22' unit could get by with a 13k unit.

Thanks,
Dennis

13500 is fine for that size. As colliehauler brought up if you oversize you don't get enough runtime for humidity control which is a big part of feeling comfortable. You will feel cooler at 75 degrees and 30 percent humidity than you will at 70 degrees and 60 percent humidity.

26' Heartland, 95 degrees, and the 13.5KBTU A/C handled it. But it really worked hard.
