Jim and the list,
We had an offlist exchange, and I too have had a singular lack of success,
except at the VW dealer.  They gave me a VW part number (255 070 525B) for
the knob for a model 182B, and would cheerfully order it in for me.  The
hooker, it will cost me over $30 CDN plus 15% sales tax.  I too am now
chasing the local Dometic service people to see if I can get a cheaper
price there.  I am also going to scout a local 'old-time' TV-Radio repair
place and see if one of the old long recessed-shaft knobs he may have in
his junk box will work as an interim measure.

Cheers,

Ted Hoekman
