That is the truck my dad has been building for the past 10ish years after he sold his class 8 truck in the late 90's when I was born. We got it running august of 2011 and plan to race class 14 hopefully in the next few years once all the bugs are worked out and a few more things are upgraded on the truck (better cam, buy bypasses, etc). Here is a bigger/better picture of the truck.
