With the truck just idling, the temp gets down to 46'ish  Going down the road or stepping on the gas to bring the idle up will bring the temp down to 42-43. That's ICE COLD.
However, getting stuck in traffic for an hour or so, you can feel the temp difference. I still want to try the fan trick.
Paragon, why won't the fan idea work? Even GM's on their Yukons had a Service Bulletin to add a supplemental fan when the vehicle sits at a light. Any air flowing over the condensor should help. I know the H2 doesn't have the greatest mounting place but isn't there a way to make some air go over the condensor?
Thanks,

That's what the guy at the fixit place in Texas said. Something about the RPMs of the truck being too low and building head pressure and the compressor not operating at the right efficiency or something.
I don't know if it will work or not, personally. He said that many 6.0L are idling too low for the compressors and I kinda half-assed believe him because I can increase the RPMs while stopped at a light and the A/C gets cooler. Other than that, I dunno.
