Good advice in this thread. I recovered my truck, unknown to me, after three days of PM and a few small repairs and drove it long-distance. I had never driven an M35 before (but numerous other, bigger, trucks). It was in the summer. Nevertheless, I took a significant risk and I knew that. I did not have a buddy, nor a chase vehicle. I would not have done it if working on the truck for a significant time at the departure location had not made me confident that I had good odds. Disassembling the brakes afterwards, at home, showed me that I was indeed playing the odds to some extent. It also taught me that I want to rip the drums off any Deuce of unknown condition before I drive it anywhere, rather than simply checking for leaks and adjusting the brakes. During the recovery, it developed a rad leak that it did not have before - fortunately, very high up and it did not slow me down.
Is your prospective truck currently being driven in road salt? Is that your intended use for the future as well?
My Southern truck has never seen salt and I am adamant not to be the one introducing it to our Northern road salt and winter damage.
