Well... at least I can recover, as the plate says, "15lbs of R12" out of it if nothing else works.
Man, this thing is heavy. My loader would barely lift it off the trailer.
I'll let it set upright for a few days and try to turn it over with a wrench. If it works I may just use it to cool a shop someday. (project #268)

Its that diesel disease one gets from owning an old diesel MB. Otherwise, I would not have hauled this thing home.
