We have had Flint leaned over pretty far a couple of times and it is an uncomfortable feeling.
The picture below is not my van, it was copied from a link found on the Sprinter Forum. I printed it and measured the angle as best I could, that is my note saying 28 degrees in the lower left.
I have looked and have never found any documentation as to the measured tip-over angle for one of these rigs. I understand that speed or a wheel on a rock can change things quickly, but this is a base-line number I would like to know.
Bouncing around off road, 20 degrees is about as far as I want to push it.
Anybody have any input as to what the "real/documented" number is? Please include sources. Beyond that, how far are you willing to go?
