Just read your build, your blog and website and am very jealous. You are living the life!
I am working the 9-5 now, we'll, i'm lucky it's not 9-5, but it's stable, secure and routine. I work with lifeguards during the summer and have late fall, winter and very early spring with slow passed work. However, i have a 18 month old son and i can't imagine uprooting for that long with him and my wife. Though, it's been done by other families on this site before.
What i think i may do, hoping to learn some of the things you did…live in the moment, watch the sun rise/set, etc. is exploring the US with my son, my Tacoma Prerunner or Subaru Forester with a RTT. Come summer, i'll work on making one of our vehicles stateside friendly and in the fall, explore the US.
Anyways, i'm rambling, but want to say "have fun!".
