RCP57,the Cat trucks were still being used in 1980. When our barge sank,the 40-87 and the 40-92 went down and I was asked to take over one of the Cat trucks. I left CZ then went onto the highway. Another driver took the Cat and was lowbedding a brand new American log loader,a miss calculation on a corner saw the loader fall off lowbed before it put out its first load. Cat trucks were good but Pacific and Hayes were better. I will search out some info as to where they ended up. Back then these trucks could go on the highway from 12:00am until 6:00am for moving to different location,a federal offence now.
