i'm really thinking about doing something about my craze for alternative fuels - specifically, a bio-diesel powered westy sounds like the best option.

my question is:  since you don't see many of them, how long were they made???  were these produced until '91 like the gasoline powered vans?  thanks for the help - i tried to do some quick searching online but thought that i'd simply ask the pros.

thanks!
dusty.

PS - what will westy owners do when/if our oil supply runs dry?  will somebody figure out a way to run an alternative fuel through our gasoline engines???...........i ask myself this all of the time.
