Dex-col is a organic based coolant which makes it
phosphate free and it will not corrode the heads on a
vanagon.   I would not think any coolant is good for
100k miles so changing it every few years is a good
idea.   When switching from a different kind of
coolant it is important to remove all of the old
coolant.   If you can smell coolant in the rinse than
you need to rinse more.   The sludge issue of dexcol
is related to a number of factors, coolant used too
long, coolant, contamination with other coolant or oil
and coolant overheating.   If you can avoid these
issues with the vanagon you will be very happy with
dex-cool.   gary

They're easy to find, just google "dex cool problems".
 Here are a
couple:

http://www.geocities.com/b_gillie/dexcool_problems.html

Whether you think these are "solid evidence" is up to
you; you are of
course free to use ANY coolant you choose in YOUR
vehicle; my policy
is to use OEM coolant in any vehicle and that's what I
do in my cars
now.

My personal experience is that after switching to
Dex-Cool in a '91
Jetta I developed coolant leaks around the temperature
sensors and
between the cooling hose flange and the head.  I'll
admit the only
evidence I have that this was caused by the Dex-Cool
is the timing.
