Not exactly a Kenworth, but I do a lot of work on these, as well as some driving.... front two axles steer, makes things a little easier....

And I drove a 5-ton M923A2 (basically a Milspec Freightliner) w/ 6-wheel shop trailer from Kuwait almost to Tikrit, Iraq... That was fun, but not the being bullet-food part.... At least the little Toyotas that infest the Iraqi countryside got outta my way!
