I had to drive 5 hours up the road to get a chance to drive in wintry conditions with the TC. We loved it. With all the extra weight in the back, we were going where others dared - most of the time still in 2wd.
Came upon a severe hill down under a railroad. There were about 10 cars sliding around trying to make it up. I just waited at the top until they gave up. That's when I dropped it in 4wd, went down one side and up the other without slipping a tire - weaving between all the stuck cars.
Just have to remember to slow down and take it extra easy. Another nice thing about traveling with the TC, if you do get stuck because of conditions or other idiots, you have a comfy place and food to wait for rescue.
