I guess my thermometer is wrong. Today it read 83, ambient air was 113, set on LOW. Old unit, 115 ambient resulted in 95 set on HIGH. Both are Coleman TSR 13.5. Both had clean condensing coils.
I think you're missing Doug's point. An RV air conditioner recycles the air in the coach. It does not pull in air from the outside, so the temperature of the air outside the coach has no bearing on the temperature of the air coming out of the air conditioner duct. To get a more accurate differential you need to measure the temperature of the air entering the AC system intake duct and the air coming out of the cooling ducts.
An automobile air conditioner on the other hand does draw air from outside the vehicle unless the selector is set at MAXAIR. In this case there would be a relationship between the temperature of the outside air and the temperature of the air coming out of the cooling duct.
