Hey, thanks a bunch for your responses, guys. It turned out it was in kind of a weird spot (at least for the guys here locally), but thankfully it wasn't under the dash or anything. The leak was in a condenser hidden (in front of? behind? I dunno) by the radiator.
Thanks again, guys.
So my dealer's been looking for a freon leak for a solid week now and they say they can't find a thing. Is there some weird place they should be checking?
Truck was also repaired after someone hit the bed and the back tire. Kinda curious if something could have been disconnected and reconnected...
