Spent the last hour with the A/C tech. Short story is that it works now. Blowing air at 37-39 degrees. I had imagined my truck being like a fridge, but I will have to live with it just being cool enough.
Long story. The first tech put a pound of freon in the system, then noticed there was far too much pressure and stopped. He said to get an electric fan, which I did. I got this one:
Flex-Lite Black Magic 180. It fit my 55.2 perfectly and you can actually feel the air being sucked in through the condenser and radiator! Took it back and they filled the freon to 2lbs. The pressure was fine but the air temp stayed at 48 degrees. We called OldAir and they said to reduce the freon a little. The air temp dropped down to 37.8. The A/C guys looked around the cab and decided that I need to insulate the cab better. "It's like cooling a tin can with holes!" he said. So I'll set about doing as much insulating as I can. The temp in FL today is 89 and I was nice and cool in my truck. Makes for much nicer driving experience.
Thanks for all the help!
