Useful info here, folks
I just came back from living in my van for the week. Went to Detah Valley and the Sequoia National Park. I feel like I was just getting dialed in and had to go home. It's the same feeling I've had for many, many trips.
This thread is going along nicely and I can see from others that it can be done. Just put all the "stuff" in storage and go underground for a year or two. It's good to see that people have done it and came back to live normal lives. Although, this sort of thing would permanently change a person. It's also good to see the dollar amounts involved in the various hiatus that people have taken.
Keep the info coming and thanks for the replies/ information.
