I think the most important thing in snow or rain is not driving above your abilities. Keep larger distances between vehicles, drive much slower, and use your brakes less. I didn't have the friction hitch. I had the Reese straight line on my previous TT. I've driven in a lot of bad weather conditions in WY. I use 4WD a lot when on hard packed slippery snow or ice on hwys. Any abrubt movement on a slippery surface can get you in trouble. Let your engine slow you down even on flat surfaces. Be careful about black ice. However, I never released the tension on my hitch.
