Pit trailer A/C unit
I'm getting a 6x12 trailer this week and I'm going to build a wall in the back and have a window unit to save some $$ over buying a roof mounted unit. I'm curious how many BTU's I will need with the walls insulated with the foam board as well as the ceiling. I'm afraid to buy one without input because I don't want to waste money on one that doesn't cut it. I live in NC where it has been about 95 degrees for the last several weeks.
I can get a 5000 BTU for $100
A 6500 BTU for $150
and a 8000 BTU for $199

Well, I have a 6X12 that only the roof is insulated but I have thick wall boards so I'm not sure how much I lose from not having the sides insulated. Anyways, I'm using a 15,000btu roof mount and with a HD strip door at the rear and Mine stays about 72 all day long. It shuts down often in the morning but by mid afternoon, it's running pretty much non-stop in 85-90 degree heat.

i spoke with my dad, he is vp of a ac company down here in az. he said a 6x12 will require a 8000 btu to be comfortable and not make the unit work so hard. He said if he were doing it he would be doing a 9000 btu, for little overkill but you wont have to worry about not being able to get to get it cool enough

The more you can afford the better . I had a 8 x 18 with a 15,000 btu roof unit here in Ga. & it ran pretty hard to keep it cool . Of course it was a lot bigger trailer . 10,000 btu should be good .

Something like this http://www.modmyrv.com/2009/05/27/rv...tart-capacitor
Basically, it works like the cap in a stereo system, etc in that it helps offset the start load (high draw) when the compressor starts. Depending on your generator the start load will be the biggest draw and if you're close power wise with running load it will help greatly. And most AC manufacturers seem to like to underestimate their start power requirements.
On that note, if you're using something like a 5000, odds are good you'll have no issues either way.
