I did check the temp coming from the vent, The outside temp was 96* and the inside vent temp was 74* with very little air volume coming from the vent.
Outside temp has nothing to do with the inside cold air output. What you want is the Temp Difference between the inside AIR return (filter) and the nearest to AC cold air output. Should be 18 to 22 degrees difference. Air return lets say is 95 input at filter. after a minimum of 30 minutes running the nearest cold air output should be 73 to 77 degrees. IF the inside of your RV was at least 85 degrees when you got 74 output, the AC is not cooling correctly. Volume may also be a problem. Have you had any work done on the AC units in the past? At this point, you NEED a Amp check of the Rear AC compressor. That will tell you if the system is charged and pumping correctly. Doug
