How hot does your truck run w/ ac on?

[great white]

That's about how mine was running, but it used to run cooler. Also the ac isn't blowing real cool anymore. Do you guys use those DIY recharging coolants or have someone at a dealer or whatever do it?

If you compressor isn't cycling on and off (ie: short cycling) then low refrigerant is not likey to be your problem.

Check to make sure your evap and condensor cores are clean.

If the condensor core isn't clean (ie: dust,dirt, mud, bug bits, etc) it won't shed as much heat as it can.

Same idea with the evap core in the dash...
