I totally agree that tire chains are the way to go. I have a set for my M37, and they make such a difference you will feel unstoppable. I have sets for my M543A2 and deuce, but have never had to use them yet. I was very lucky in that a local fire department gave me two sets for duals and a retiring trucker gave me a full set for a tandem, still new in the bags, as payment for recovering his semi one time.They are a pain to put on, but when you are going where the stuff is really bad, be it mud or snow, they are the best safety factor you can have. The problem is, sometimes you get into the crud before you anticipate it, and then putting on tire chains is almost impossible. If you can anticipate in advance, they are very good. Another problem for me with chains is that many times I have a lot of road distance to where I will need them, then a short time of using them, then road travel again. I do not like to wear them out with a lot of bare road time, so I have to decide if I want to put them on to just take them off again. This is why the lockers mentioned and single tires are also very good in my experience.
