Reading about Allen and his hauling, thought I'd tell you about my granpa (who's been gone more than 40yrs) that was in the bulldozing business. He hauled a D6 with a 2 axel steerable lowboy with a pintle hitch behind a 2 ton truck. Just drive it on over the side and twist her straight and set the brakes and good to go. Never a sign of a brake on the trailor. He always had IHC trucks with 6cyl engines. By the time he got to the top of the hills, you could count the engine revs and he would spit tobacco in a can then shift gears. Boy I loved going with him to get a chance to run the dozer. He knew what hills he could pull and if he couldn't, he would jump it off and run it up the ditch to the top and go back and get the truck. I won't even go out of the driveway without a box full of chains and binders. Things has really changed in my lifetime.
