I have used deuces and 5 tons on the farm for about 30 years. I haul grain, wood, stone, fertilizer in bags and seed, etc. I highly recommend them as a farm truck. Chains in the bad stuff, at a minimum on both rear axles really makes a difference. It depends on what kind of mud you have whether the space between the duals will pack full, really limiting traction. The chains help that, or I used to take off the outer set of wheels on the tandems to cut through better when snow was really deep. I had no stability problems with them off in normal use and sensible driving. I suggest also turning up the fuel setting from what it is from the government. They are dogs when you get them. Turn the fuel up and it is an entirely different truck without compromising longevity when driven by an operator who knows when and how long to use it. We also use them to pull gravity wagons and implement trailers.
