Ouch!  How much of that $1500 is the new compressor?  The fittings, seals,
and coolant should be pretty inexpensive...  If they're replacing hoses too,
of course, that will set you back a considerable amount.  I have one leaky
hose, which I'll have to replace whether I do the R134a swap or not.  :-(

Something with more capacity?  Like what?  Did they have recommendations?

Have you looked into FR12/Frigc?  According to Pennzoil's Web page on it
(http://www.frigc.com/), there are a ton of places in Houston that can
install it, and they claim that:

- it's more efficient than R143a
- it doesn't require any equipment changes

I don't anything about it beyond what they say, of course, and I don't
expect them to be wholly objective.  There isn't an installer for it near
me, so it may not even be an option for my bus.

Amen, brother.
