I am excited for my friends and they have both done such a good job of converting the Airstream. I wish both of them lots of luck when they finally get finished and open their new venture. They are both great people. They soon will be living the dream of operating a WFO in an Airstream. Both Bob and Steve did build their own WFO's at their home. Both of them are so handy in everything they do.
More on Steve's oven builds at http://learningknowledgetomakepizza.blogspot.com/2012/06/steve-my-friend-man-with-many-pizza.html Steve is a man with many talents. So is Bob. He also built a WFO on a trailer and a Weber conversion. I don't have the pictures of Bob's Weber conversion, but his WFO on his trailer is posted on my blog. I really like Bob's Weber grill to pizza oven conversion!
Now Bob and Steve have illumination! Lights on. :)
