We ordered our Sunnybrook 31BWFS with 1, 15000 BTU Penguin A/C and it only cools down to about 76 or so on hot days. I would have ordered it with 2 units but I store it in a building and only have about 2 inches of overhead clearance with the single unit mounted in the living room area. The dealer told us 1 unit would be fine but I think I might need 2. Anybody have a 32 foot or larger fiver that will easily cool down to 72 when it is 95 degrees outside? I'm wondering if need be could I install another unit directly behind the original and connect it to the existing ducts and thermostat or maybe just use it as a direct vented unit for the living room area. If I did this maybe I could close the living room vents on the original and use it to cool the bedroom and bath area and use the add on unit to cool the living room. Thanks for any advice.

Generally the second unit is a non-ducted unit. The ducts cut into the ceiling are not large enough to handle the additinal air volume of a second unit. You need to be careful closing off vents as you may reduce the air volume through the unit and cause freeze up problems.

Have you got insulating covers for the vents? Also, cutting the foil backed bubble insulation to fit windows will help reduce the load as well. Your best friend is shade. Keep as much of the trailer as possible in the shade during the hottest part of the day.

A 32' is pretty much the limit for one A/C unit whenused in hot climates and direct sun.

If you are getting a 20 dF difference between the inlet air and the outlet air, the unit is working as designed.

As for cuttting a hole to mount a second unit, I noted the ducts are two small plus, the roof is not designed for that much weight in the one area and probably not braced.

Have all your windows tinted as dark as is legal in your state. This will do wonders for allowing efficient cooling and heating of your unit. Plus allow for day time privacy.
