Here are some pictures of my 1990 F-800. 429 4V with Allison AT 545 auto, juice brakes. Has a National Crane 456A (10 tonne, 56 ft of stick) mounted on it. I was actually in the process of replacing my '84 F800, also a boom truck when I found this one. Was looking at new or close to new trucks, but this one was in great shape, 63000 km ( 38,000 k miles), and 1600 original hours on the engine. Repainted cab and bed, crane had just had complete service and rebuild. Replaced the front passenger spring, and the starter was a little tired. Since buying last year, put on about 150 hours, and rebuilt the ignition system. Truck had new tires on it when bought.
The only problem I am having now is that the speedo and odometer have crapped out. Suspect it is the speed sensor, but having trouble finding a new one.
