I've got the Michelin xzl's they are the middle ground between the tire types. Michelin says xml are for sand, mud and loose ground. Xzl's are their all terrain for tactical vehicles and longer lasting. I should find out this winter how they do. In reality when conditions get bad, slowing down and chains will be used. Lmtv/mtv are no Subaru. High center of gravity, weight, fat tire contact surface, and inertia are not factors that make for a good snow runner. Lockers , awd, and all the bells and whistles that can make you go in the snow, do nothing for breaking. Snow tires are generally narrower to have higher ground pressure to push snow out of the way. If this is going to be a daily driver then stud the tires, especially in hill country. Going down hill in ice and snow covered roads in a heavy vehicle is no fun. And when you slide off the road these vehicles are a lot more likely to tip than a car is. Growing up in VT I've dug out of more then one snow bank, and glad that I live now where I don't have to deal with the snow as much, but I can drive to it year round.
