Don't forget to buy a power engraver to put your name on everything which is only a little protection from thieves. Get around a job site with 10 different subs and other strangers walking around and things get lost occasionally.
If this cargo van is big enough, build a rack or a rail type slide so you can slide out an interchangable home built stand for a table saw/chop saw/router/sander. One of the biggest chores is setting up the tools to do a simple job and hauling them back all the time. Just slide it out the back door, plug in, and start cutting.
