I am looking for a high-top long passenger van to haul my travel trailer. I live in snow country in Southern California (steep roads-Idyllwild, CA). I am amazed that no one offers AWD in these vehicles. Having come from a career in technical publications and having lived in the snow for more than twenty years, I find AWD not just somewhat, but far superior to 4WD. A good example is that more than 15% of the vehicles where I live are Subarus. Someone should pay attention.
