My guess is it's going to be stock-friendly, but perhaps not 2WD-friendly. Tony Huegel's guide books are designed for the average SUV owner who actually has an interest in finding out what the t-case shifter is for. Remember: that trail we visited right after the Xterra Championships was considered "moderate" in his book. The Barker Pass Loop (not Dollar Hill) is among the "more difficult" trails featured.

At the worst you may need to remove your step rails and mud flaps.
