[AT] smoking/gas bottles, now O.T.

Fri Jul 8 15:08:08 PDT 2005

I can't figure out why GM isn't offering the Duramax in the Avalanche, 
Suburban, Yukon, etc.   I guess it is possibly a supply issue.  As much as a 
loaded out Suburban costs anyway I can't imagine it's because  they don't 
think they can sell them.
