I have a new 280bhss with 13,500 BTU A/C. I don't think the air flow from the ceiling ducts is adequate? Weak. I have posted a video on YOUTUBE that shows the air flow. IF you could view and let me know if your air flow is any stronger? Link for youtube is below.....

Typically, a properly operating A/C unit should have an air temp drop (delta-T) across the cooling coil between 15 and 20 degrees depending on several variables IE, humidity, really high outside temps, system design etc. Check the entering air temp at the intake(return)and then the air temp at one of the grilles using the same thermometer. This is the best indicator of what your unit is doing. The readings should be taken after the unit has run for a while and be careful to avoid getting short cycled discharge air from a close grille back into the return when you take the entering air temp. High humidity will reduce the temp split as more capacity is used removing moisture and higher than normal outdoor temps can also affect the split some. A drop higher than 20 degrees indicates poor air flow which can cause your coil to frost over, less than 15 degrees, poor system performance. These readings will change some as conditions change.

Make sure you have the flaps closed on the main unit inside the camper
There should be plastic sliders

I have a 32bhs, and had the same problem with air flow. I took the interior cover off of the unit, and found the baffle between the supply and return had fallen over letting most of my cold air go out the roof. I stood the baffle upright, and installed a couple of screws on each side of it to keep it upright. I also took out all of the ceiling vents, and sealed around the duct with foam rubber. A lot of air was escaping into the ceiling space. By doing both of the above, it made quite a difference in air flow, and the amount of time the AC was running. Much better now.
