It's Kool! It's Nostalgic!
At the end of the day is still a 40 year old VAN that drives bad at best do the 4WD conversion, is not very comfortable and is really only good for a short weekend trip. It's going to break as all old vehicles do and that is always at the worst time.
At the current $30K bid price you will have Much More Use, Much More Comfort and a Much Better Driving Experience with a modern 4WD Sportsmobile van.
Kool and Nostalgic only go so far!
