I have a digital electricians thermometer that I used and the air coming out the vents was about 65 to 71 degrees, so I took the inside covers off and shot my meter straight into the fan on each unit. The 13.5 unit stabilized at 15 degrees F and the 15 unit at 25 degrees F. I think the units are working just fine, but I was hoping the 832IKBS would handle hot weather much better than it did from a cooling stand point. I will be hooking to a 50 amp outlet this weekend and will update my post IF that makes any difference. Thanks again.
One thing I haven't seen mentioned yet is to use the vents. When the trailer gets hot open them and leave the heat go out them. Heat rises, cold air drops. This will help cool the trailer better and quicker.

I'll try this as well, thanks. Also do I run the create a breeze fan for a short while too?

Me? Sorry if I confused anyone but I'm not complaining about the trailer itself, it was just so hot in there I was worried something may be wrong. I assure you I did blow up anything in the coach.

Becareful tho if your vent is near an a/c register you'll get condensation on the ceiling.

That would not hurt. Anything that will help remove the excess heat and help cool down the trailer.

Think of your AC as a circle. It is drawing in the hot air and cooling it down a little then spitting it out to the trailer. Then it draws that air in, cools it down a little and kicks it out again. It keeps doing this till it reaches where you have the stat set to then shuts off.

We use to tell people you could expect a 10 degree difference after an hour. Of course this depends on how big your AC unit is and how hot it was when you start. The cooler the trailer is to start with the better off you are so get the heat out any way you can!

And remember cool air drops and hot air rises. So let the hot air out.

True but not if you only do it for a few hours to get down to the stat temp. Then it is time to close everything back up.

OPPS! I just went out to my RV to load it up for the long weekend and decided to cool it down from 90 degrees. So with my 30 amp garage hook up I turned on both A/Cs and left. Wouldn't you know the first thread I see was this one about two A/Cs on a 50 to 30 amp dogbone. Read a little, then decided to check my A/Cs. After a half hour of running, the temp dropped 12-15 degrees and both units were running strong. But I did shut one down just in case.

Well, we let the one 15000 btu unit run all night, it was drawing 15 amps from a 30 amp breaker, it showed the inside of coach to be 60 degrees at 6am, but when my wife checked it, it was 87 degrees at 4pm, that was just 6 degrees below outside temp here. I dont want to run both units at the same time at home on 30 amps, so we'll try again when we have 50 amps at the park and see what happens.

I ran both of mine on a 30 amp pedestal back in June. Didn't turn on anything else while both were on. If needed anything else just kicked one to fan and did my business. Had no issue keeping her cold.

I hope that on a hot day, especially, you keep and eye on your voltage. Overloading a line may not blow the breaker, but that, and a whole bunch of RVs in a row running air on park power will surely pull the voltage down and then things labor harder and run hotter and less efficiently; until no tell when but surely they will fail prematurely. Progressive Dynamic power protector, Hughes voltage manager or at least A BIG VOLT METER.

Good luck out there. Tom
