Fullsize vans don't offer AWD at a reasonable price point.
Either AWD/4wd is necessary when you're going to other people's property because you can't guarantee any given property isn't an icy shithole and when you're a professional being paid by them to be there for a specific purpose the last thing you wanna do is slip out trying to do a 25-point turn on their stupid sloped driveway and put a tire in the landscaping.
