Our Deuce was DRMO'd to a Volunteer Fire Department in 1991 after a TOTAL rebuild at Toole, Utah. When they picked her up, she had 5 hrs & 30 miles on the gauges. Average usage: 6 miles per hour!!!
After she served 20 years with te VFD, we bought her with about 920 hrs and 10,200 miles on her. Subtracting the original readings, the VFD put 915 hrs and 10,170 miles on her. Average usage: 11.1 MPH over a 20 year period ! ! ! And averaged ONLY 45 hrs, 45 minutes PER YEAR ! ! !
Let's consider some contributing factors here:
1. She served as a Brushfire Truck, so only occasional use and much more idle time than road or off-road driving.
2. Schleicher County Texas is VERY rural, and about the size of the entire state of Rhode Island, so, when she was driven, the distances were often significant... a counter point to the idle-time factor.
3. In a single MAJOR EVENT, y'all may remember when the State of Texas raided the FLDS "religious" compound (it made the national news) and "rescued" hundreds of children from a cult bent on sexually abusing kids. This truck stood that duty for the entire duration of the RAID and the WEEKS following as the investigation and collection of evidence was conducted..... LOTS of idling time, though not run for the whole time!
