stick a temp gauge in the vent ,should read 42deg if its much from that its not right.
WRONG. This may be true for Automotive and Pick Up trucks, but is NOT even close for a Class A Motorhome. The FACTORY specs for a Class A Motorhome is 60 degree output at the nearest vent to the evap core with ambient temp above 70 degrees. . That said, most Class A's will get below 60 and even down to 48 to 50 degrees in sub 95 temps. Below are the 2 links for the BEST diag of Motorhome Dash AC systems. Doug
