The R-12 alternatives I've used are Autofrost and Freeze12. I used the Freeze12 in a 71 Dodge truck, factory AC w/York compressor, and it was ridiculously cold, even in Oklahoma summer. I've had Autofrost in two systems, my 69 Chevy truck, also a York, and my Gremlin (when it was a York).
The air conditioning on most all vehicles including Wanderlodges was R-12 until they changed to R-134 in the early/mid '90s. It can be recharged with R-134a I'm told, but will lose some cooling capacity (with a new air-dryer etc.). Mine works very well, and at 18,000BTU I would never abandon it.

I believe it costs $30-$40 a pound, and most cars use between 2 and 3 pounds. You can have your car converted over to R-134a which is used be most all vehicles today.
Oct 16, 2012 · So what do you recharge an older air conditioning system with if R-12 is unavailable? DROP-IN Alternatives FOR R-12 REFRIGERANT?
