I injured my lower back probably 40 years ago. I fell out of a semi trailer and landed flat on my ***. It screwed me up pretty good. And like a dumb *** I didn't go to the Dr for it. I just powered through it with Tylenol and Chiro treatments. It worked but it took a long time to heal. 28 years on the tool truck didn't do me any good either. Step vans are like your Tractor. Sit right over the front wheels with a straight axle and a 6" stack of leaf springs. :BangHead: :BangHead: :BangHead:
