I was also thinking of also converting to R-134A,but after talking to an
owner of an auto A/C repair shop I decided not to do it.  He said that
the conversions were going very well, but that R-134A was not as
efficient and that new R-134A systems from the factory use bigger
compressors and larger condensors in front of the radiator to provide
the same amount of 'cool' as compared to R-12 systems.  He was not sure
if the large interior of the Vanagon would be cooled enough with R-134A.
We do live in the desert of So. Cal. where 110 degrees in the summer is
normal. The price for R-134A was also the same as R12 last summer.  So
the only benefit is to the ozone layer.  IMHO not much of an 'upgrade'.
