All of these trucks belong to the Pope Materials Company stationed in Georgetown, Texas. I spoke to the owner, and he gave me the information about the trucks. Each truck costs between 250 and 275 thousand dollars. The diesel engines themselves cost 40 thousand to replace and ruin about 700,000 miles. They are all equipped with GPS which gives the owner information on their location, speed, whether the engine is running or stopped, and other information on engine condition, etc.
