We have a 100k here and it is destroying the secondary roads. The state can't keep up with the rate of deterioration on their roads either. Going from 80k to 100k didn't do the roads much good and I don't think it's going to save the paper mills.
Made boats called Garwood. Mead Morrison was a division of Garwood by 1940. That style of winch was found on trucks that moved artillery. The Dodges had front winches rated around 7500 lb pull that 3MB is liable to be considerably more as they were found on fairly large 6x6's.
