You're cheating with diesel...
My area of California is in the northern central valley where 115F days are fairly common in the summertime. We have a three to four week spread in July and August where if the temperature is below 100F, then that's a cool day.
I don't believe there are any restrictions on HC refrigerants in California, but I'll do some more digging. Since Cali is making a big push for Detroit to accelerate their alternative energy car development, I doubt there'd be a ban on natural gas powered vehicles (or refrigerated ones).
My main concern is that my system came out of a small vehicle and is going to be used to cool a large one... I want the largest temperature differential possible without freezing up the unit. Both of my current vehicles are R134a conversions and I haven't been too happy with the results versus the old R12.
The other bonus of HC refrigerants is that your average backyard mechanic can handle them. R134a is not available to the general public without proper licensing and evac equipment.
This is of course all information that I've gleaned from researching it on the internet. I have no personal experience with HC refrigerants. Just wanted to make sure everybody knows that (don't want to sound like a false authority).
Actually you can get R134a at any parts store, it is the earlier refrigerant (R-12) that you can't get any more...
