On the GT, I've only ever had to use a strap to pull my land rover out of one of our camps. But that was only because it was loaded down and I didn't have the bump stops installed yet, so the rear would jam into the wells when I had to get out of a rut. Other than that, we have just had smooth trips. Lots of little places to stop off at, small towns, waterfalls, etc.
We are headed down parts of it this weekend, just to view the leaves. Thats about the only time we hit it.

Multiple routes, its always changing. So the GPX is updated often by Jeff Stoess, he takes paypal donations, in which he gives out stickers as well.
