Haha I actually saw a build up on pirate a few years ago where a guy was SASing a Chevy Astro van. Definitely not the vehicle I would want to dump a lot of money into, but he had a big family and needed to keep the minivan, so he did a build up on it. Actually did pretty good work, though I dont think this is the same one. Whatever floats your boat 
I admit I do like those ford straight axle 4wd vans. Always thought it would be kinda cool to have a mildly built one, kind of a camping or hunting rig. There was one in petersons a while back, it looked pretty sick for a van.
At work there is one of teh old Econoline vans and it has "Pathfinder 4x4" on teh side, with a mild lift, ill see if i can get a pic this weekend. custome conversion or what? i think it has a 14bolt rear...
