You're in a great place to start from. Just a good sound Van that can do some road work, a basic bed in the back, a small kitchenette with stove, sink, water, and an ice chest could put you on the road. Having a Cell Phone, and Laptop would be great to have along.
I have a couple of sites right below that you may find helpful. One is about converting a Van and the other
a portal of handy information to use for planning before you leave or navigating your way with, once you're on the road.
