Hi Y'all,

I'm working all out on my SP-36 getting ready for our last coast to coast trip
(I think).

The coach AC is weak and needs charging. Did the 1990 SP use R-12 refridgerant?
and has anyone used the new Freeze-12 replacement. It is supposed to be
compatable with R-12 but I guess the remaining R-12 should first be purged from
the system. I sure would appreciate any suggestions.
