One thing you might try, There are 2 settings on your AC. One pulls the hot air from outside. This setting works, But if it is really hot out it doesn't work as well.
The other setting re-circulates the cab air and cools it further. I tend to start this setting to begin with then change over to pulling the fresh air.
Other than that, Maybe your losing 134a. Have them do a pressure check.
kinda off topic, however, This made me realize something else, I don't really notice any MPG drop with the AC on. Last trip with the A/C on the whole way I saw a .5 mpg drop. This was by doing the full math and not the trip computer. This is gotta be the first vehicle that I have ever had where I didn't lose a full 2mpg's.

I know other Mega Cabs have reported this problem... I have an appt to have it checked AGAIN this week, but I don't expect them to do anything, they will just say it's in spec. again.
As for MPG, V-8's typically don't see much of a MPG drop from A/C, it just doesn't drag them down enough, unless you were fully loaded in the bed and/or hauling a trailer, then I could see an MPG drop. I only get 9MPG anyway..
