This is that video from April, 2015 the month the 4x4 first came available. I was at that forest in late March helping with the Maple sugaring collecting and there was two feet of snow. So that field had to be a mud quagmire with a very recent snow melt.
The extra 3" to 4" ground clearance would be a plus. I would be more interested just to have more assurance driving on beaches. The debit side is it puts the van over the magic 10 foot clearance mark. I would never attempt to drive into a muddy field like that video. I don't see it for off-roading period given the investment and the delicate interior storage of a typical B.
