I recently returned from a trip to Dallas, TX, with the High School Robotics Team where they were participating in the VEX World Robotics Championships. In our daily commute from where we were staying in Garland to the Kay Bailey Hutchison Convention Center in Dallas we traveled on the construction site that is also know as I-635. Being a truck modeler I was particularly interested in the equipment being used, and one thing I noticed was that most (if not all) of the dump trucks being used on the site had sleeper cabs. My first thought was that they might have been tractors converted to dump trucks, but I don't think that's the case as it appeared to be across manufactures & companies. I wish I had gotten some decent shots. Perhaps someone from Texas could explain why they do this.
Thanks.
