I must say, my newly acquired Big Horn manufacture date 7-19 is pretty cold. Wife freezes me out during her hot flash episodes. I'm thinking with such a late build date they finally fixed the problem others are having. Now we are supposed to be getting in to some hotter weather this week, I will see how it does then.
Mine seems more than adequate. We’re seeing temps in the 70s...just before dawn. And we’ve been out of the triple digits for a day or two! Chilly.Ha ha, get ready for the guys in 70 degree climates to tell you your ac is just fine because theirs is. I am telling you now this AC problem was the biggest reason I got out of my truck. I cried inside. I was so excited to get the 29 Limited. I worked so hard to be able to buy that truck and the loss I took on it was enough to break anyones spirit.

This is excellent! Thanks!FROM THE RAM 1500 (DT) SERVICE MANUAL
- With the A/C clutch engaged, compare the air temperature at the center panel outlet and the A/C compressor discharge pressure (high side) to the A/C Performance Temperature and Pressure chart. The A/C clutch may cycle, depending upon the ambient temperature and humidity. If the A/C clutch cycles, use the readings obtained before the clutch disengaged (coldest temperature).
