COOL! I have not looked at that on the jeep sight for a long time, but it never used to mention specific trails.
I have been to on of the traveling jeep demonstrations where they let you test drive different jeeps. they usualy have the standards listed there. I cant remember all of them, but the water fording is usually 19-22 inches depending on which model you get. My wife's patriot is 19 inches for sure. I think 4LO is part of the requirement for the trail rated badge.
