Chains? Yes. Snow tires? No. Handling? I've driven MCI and Crown buses (hauling prisoners). I've also driven gasser MHs. I learned how to drive on snow and ice. I had training driving on soap covered track. My thoughts. On a slippery surface a diesel MH tends to lose traction in the front because engine is in the rear. Steering gets erratic. The MH may not react to a quick steering movement. A gasser MH seems more stable front and back on a slippery surface because the engine is in the front. However, if you break traction with a car or PU you can turn into the skid and it will recover. (maybe) If you break traction with a long vehicle like any type of MH, Gasser or diesel, it is pretty much over. You just don't have the turning radius to recover. In a MH it becomes much more important to gear down and stay off the brakes on slippery surfaces. In addition keep steering movements to a minimum. Black ice on shady mountain curves can turn into a nightmare so driving becomes much more tiring. Chains? They now sell cable chains for busses that qualify commercially. I carry them anytime I am on the road in the winter months. They are much lighter than link chains and easier to install. Installation on outside rear duals. Hope this answers some questions.
