I have always found that Dodge vans, while very reliable are the least soundly built. Ford and GM have always used a full frame under their full sized vans where Dodge opted for unibody construction. This is probably a factor in their being able to sell them for a lower price but it also means that a hit causes much more serious damage or even a total where the others will survive.
I know that TELCO's use Dodge vans pretty much exclusively but I wouldn't take that as a recommendation. It's probably only because of the lower cost which adds up when you buy by the thousands. FEDEX is probably doing the same thing.
