@Mein Sprinter hard to say. I’m new to the Sprinter off road. There were no 2 wheel drive vehicles a the lake. There were a number of spots where the van struggled to get traction. If you are going to try it I would recommend going with another vehicle with adiquate recovery gear.
Here’s a short
video my buddy put together. There’s a short clip of one of gnarlier sections at around 3:40. You can see me getting out of the van contemplating on whether I should turn back or not

.
Also, on the way back there was a section where I was on two wheels, driver front/pass rear. It did require throttle to get out of it. Not sure how 2wd would do in such a situation. I wish I had stopped for a pic, but there were 3 trucks waiting for me to get through.
