A/C retro fit.

I'm using Enviro-Safe in my Dorf Ranger. Excellent product.
I plan on using it in my CGT as well.

R-134 is not truly "safe for the environment". It is, in fact, toxic. Oh,
and it can be flammable:

This is true. A charge of about about 12 oz of propane/butane isn't much to
get excited about though (yes, you use less than you would R-134a). In fact,
it is very widly used in Europe. It is sometimes used in much higher
quantaties in truck refrigeration units. Hydrocarbon (propane and/or
butane)refrigerants are used in homes and commercial buildings (R601 for
example). And many vehicles are fueled by propane, from cars to fork trucks
and lifts.
