I have seen some of these that are pretty nicely done. A few thousands dollars paint and body work and you would be surprised at how nice that first van could be. The top is only fiberglass, it isn't that hard to fix.
The chassis is the same as a F650 Box truck I don't think any of us are scared to drive pass those and this is lighter and easier to stop. It probably has a cummins with a Allison automatic.
I have almost bought an F650 excursion done in a similar fashion, but they ones I have found weren't done well or were too far away.
I would buy the van above in a heart beat if it was priced right.
Take a closer before you write it off. It is not going rock climbing but it can do a lot. Think about how many hot shots truckers would kill for that rig. I see a lot of these guys living out of F350s.
