Has anyone ever done a conversion from gas to diesel?

I have had Diesel rabbits and Jettas for many years now and I have also had
my Vanagon.   I love my Vanagon and even though I promised my wife 2 years
ago I would sell it.  I still sits in the yard waiting to be reawakened.
There is nothing wrong with it.  I just changed jobs and I now commute about
120 mile aday.   Cost too much to drive that kind of distance so I got a
diesel Jetta.  50 MPG at $1.08 a gallon works out to a lot less bucks a week
in fuel.  Well my long commuting job may come to an end soon and I will fire
the Vanagon back up.

I love my van but I wish it were diesel.

Has anyone had a Diesel Vanagon go over  100,000 miles with no major
failures?   The Jetta has 210,000 and goin strong.  I realize the van has a
hell of a lot more frontal area and weight.

Oh Well

Thanks for listening
