What he's saying is that at the best of times the temperature difference between the incoming air and the treated air is 20 degrees F.
I've heard this before, even from HVAC guys, and it's just not true. 20 degrees difference refers to the best an RV air can do is keep the *entire coach* at 20F below ambient.
Unless I have some sort of magic a/c, yours should also measure 50+ degrees or so at all times. I measured mine with 90+ ambient. Put your hand on your car or RV a/c vent. It's a lot colder than 75.
