My 06 seems fine. It's been really really hot here in Toronto the last week or so and I just set it to MAX A/C and she's cooled down within about 5 minutes and I have to turn it down to the 1 setting. Sure it takes a bit longer to cool down but it has a larger area. The only thing that I miss from my last 2 vehicles was the auto climate, which is a great feature. If they had at least added a couple of vents in the passenger area of the truck it would probably help alot.
