I used the '76 GMC plow truck for the first time today! Didn't get stuck hardly at all, although I did go to the hardware store and buy half a ton of tube sand for ballast. That made it at least useale in the snow, although when the dually tire chains get here, NOT legal for highway use here in Michigan, I'm sure it'll be unstoppable. It did blow an O-ring in the valve body, which lets the blade drift, and loses fluid at an alarming rate, but the rebuild seal kit that's also on the way should remedy that.
Now that this plow truck project is (almost) finished, I can get back on the Diamond T, and the Tini-Home canned ham (canned HAMB) trailer project!
