My truck driving teeth were cut on a Mack B-61's with Duplex and TriPlex trannys. After that I drove dumptrucks with 5+4 for some real gearjammin' fun.When I bought my own tractors I mades sure the had RoadRangers in them. I loved that old RTO 913 behind the Jimmy 318. Just slam the door on your finger and get good an PO'd then climb in and put both feet flat on the floor. Those double breasted Yamaha's needed every gear you could throw at them.
