Air conditioner question.

[Walt]

I own a 2010 MS 32RS3. The few times I’ve used the air conditioner it doesn’t seem like it is cooling the trailer down more than 8-9 degrees below the outside temperature. I’ve taken the shroud off the unit and everything looks okay. Should I expect more than 8-9 degrees lower than the outside temperature? I just got back from Yuma, AZ where it was upper 90’s and inside the trailer it was upper 80’s. Not much air is coming out the inside vents and especially the bedroom vents. Any ideas?
