Atsrmf,
I don't know where Indio is, but if it is not in California, look up a refrigerant called HC-12a. It is a hydrocarbon based that is completely compatible with all things R-12. It is almost three times better then R-134a at heat pumping and is completely non-ozone depleting.
But, (like HC-134a) it is flammable. There is an advantage there in that if R-134a burns, the by-product is extremely toxic.
HC-12a is a combination of pure (not cooking grade) propane and iso-butane (iso in this case means the molecule is a different arrangement) I have used this to great success.
If you are afraid to have several pounds of flammable material there, then think about the amount you already have in the LP tank and fuel tanks.

I have heard of this product and seen it in parts stores, but have never talked with anyone who has used it. For a big solar oven such as a Class A motorhome, this might be the stuff to use. The fire hazard is the ONLY setback.
