There have been a lot of threads asking about AC's; size, how many etc.
I want to give a brief? synopsis of my experience with this trailer over the last 3 summers.
*If you are close to 30' or more get 2 ACs. No question.
*If you are buying a trailer don't get one with black sides on the slides.
*Go for lighter colors for the ACs and vent covers.
*Get frameless, tinted, DOUBLE paned windows.
*Get 50 amp service ( for the 2 ACs )
*Have a couple of fans to circulate air
*IMO get a non ducted AC (ours is 13.5) for the bedroom for those days that are just "out of bounds" so your bedroom can stay cool. (I've not had a dual zone AC so don't know if those would accomplish the same thing).
We had 2 ACs (15k and 13.5k) installed on our new trailer. I've never had a situation where I couldn't run both until today; we just came in from FL 3 days ago; it was 105 today and is 101 at 7:30pm. I can only run the 15k on our property next door since I have 20 amp service. It is about 90 degrees inside and the AC is running constantly. Checked the output from the AC at the vent and it's 60-61 degrees; seems too hot to me (our house is 51*).
Anyway, the installation of a 2nd AC seems a no brainer to me on any trailer of any size. On the other hand, my furnace (trailer) is either a 35k or 40k btu. Maybe I can find an AC of similar size??
OR, I have 2 5 ton
ACs at the house; maybe they make one about the size for an RV??
Prospective owners need to know that the things I mentioned above can help/hurt your ability to keep cool in extreme temps. Just for thought.
