There are, not sure what your qualifications for a “risen van” are, but Ford Transits and Mercedes Sprinters have an AWD variant. Dodge has had 4wd panel vans since the 90s, not sure if they still are, tho. There’s probably other makes out there, but that’s what I know off the top of my head. I think there’s also aftermarket companies that can mod vans into 4wd, but that’s getting a little crazy for just a basic work van.
