Like driving in some sketchy places...it does come down to driver skill-set and comfort level. A suggestion was made to find a parking lot and give'r? That's a good plan. Gives some idea of what to expect. But..expect the unexpected. Driving a large vehicle in snow/ice is not for the faint of heart. Unlike driving in some conditions, snow/ice is not just on the road..it's everywhere and often shoulders are no longer shoulders, but hills and wide spots one could pull off into are now full of snow. Or trucks.
I enjoy it..but I have done lots of it and am pretty comfortable. Having said that...parts of my body get all clenched up when facing an oncoming vehicle that is speeding and slipping.
