Many years in an AWD Sienna on a dirt-road hilltop. Got stuck in mud once (worst mud season I ever saw). Plenty of traction; was plowing mud before I ran out of ground clearance. Too low. Other years it was touch-and-go too many time for comfort. Put the biggest tires that'll fit and you might be okay. It's a great paved-suburb vehicle. A good dirt road van 90% of the time, just not in bad mud. Personally, I hated the thing but that's a separate issue.
