I switched mine over to r-134a three years ago (new drier, properly evacuated
system), it works fine and blows cold but does need a can or two every year.
The main problem is that it blows cold in the back while it stays really hot in
the front (this is a '83.5 Westy with stoked 1.9-->2.1 engine). Has anyone
switched the backblowerbox for a front-only ceiling-mounted version as in
some of the other models?
