During my trip to Texas last week, I interviewed a man who drafted the suspension components for the Overland Train MkII. The interview lasted only an hour. A couple of days later, we met up with another man who worked on the R.G. LeTourneau, Inc assembly line. During the 2 hour lunch, he gave me a custom slingshot. He makes these custom for each person that he deems worthy of his creations. This is built out of Red Oak and has custom engravings on each side.
