I have been in a few of they also and never seen one like this either. Looks to me like someone were having fun with his or her photo shop program. If you blow up the picture the Keep on trucking is a square transplant onto the truck. Nice job though, maybe it is real, one of those secret mission trucks. I used to hate hooking up the sleeper units, the poor guy in the sleeper would get toss around when you hit the pin. Had the fear of someone coming out of the back and strangling me, those clutches were a bear. I never like a cab over, never felt comfortable in one.
