Re: DIY Van Electrical
Definitely on the driver side. At least you have a chance of seeing you're plugged in before you drive off causing all kinds of damage. SMB cut in a door that houses all my electrical plugs and also makes a highly visible warning that something is plugged in. (you can see pictures of it at the web site shown below).
2 STR copper TW wire is a good choice and actually more than what SMB uses. I'd still run it in some kind of protector tube typical to what wire harnesses use. Weight distribution is going to be hard to figure unless you build the van first or have some very accurate measurements.
Good luck on your build.
