The truck is a single axle 2 speed dually, 10 bolt rear hubs. I dont have any info about weight, but my 59 came in at 8600. With a derrick on the back (and judging its construction,) I'd say around 10,000 to 12,000 lbs. The engine is a 292 straight six. There is an aluminum tag on the booster, but there is no inscription on it. The trailer has electric brakes, and the truck has a brake controller, one of those old rheostat types. I'll try to get a picture, I moved over the winter, so truck stuff is still pretty scattered.
