I did find 2 holes about 6" diameter each in the lower corners of the garage where cold air was pouring out, so I bought some black "great stuff" foam sealant and filled those. While I was there I went ahead and sealed the garage from the 2 propane compartments to prevent mud dobbers/wasps from getting in. I guess I'll surrender the propane compartments to them....Anyone use window screen to cover the large lower opening on the propane compartments?

More on A/c cycle issue, I found this past week end that when the temperature in my RV is within 1 or 2 degrees of the outside temperature, my A/C will cycle 5 or 6 times before it "figures out" what to do: kick compressor on and cool or shut off. If I change the thermostat setting to a lower setting by 3-4 degrees, the unit comes on, operates normally and cools the RV. The trick is to off set the "set temperature" on the thermostat to fool the A/c unit. When the inside temperature is lowered and is different than the outside temperature, everything works as advertised. I haven't had time to get with my dealer and discuss this "magic" with him. Will get back with you when I get an answer.
