TFL truck just published it's video in an AC comparison test. Ram is 52 degrees vs. 42 degrees at the vent from the F150. Despite the vent temp difference, at the end of the test...there was only a total difference in cab temperature of 1.7 degrees. Interesting despite the 10 degree temp difference at the vents between the two trucks. As shown in the test....my Ram Limited as well only has been able to reach a low of 50 degrees at the vent. So...I guess this is what Ram says is normal for their system? I love my Limited, however the AC performance really disappoints me. I hope something can be done about it. I sure would love to feel 40 degree temps at the vents instead of 50!
