The rock garden in that vid would be the HARD group and that garden is totally by-passable... I was just there this weekend prerunning on my quad. I have also been there in the Hummer. There are plenty of trails there that are Beginner to Moderate Rated that you would have an absolute blast on. And most of the Moderate stuff is really wide too.
In fact when I ran it back in August we stuck to Class 4 Truck trails. Trails are rated Class2-5. We pretty much ran Class 4 all day in the pouring rain. The only carnage we did was a 2 broken tie rods. Both on the same truck and they were running factory tie rods. I had spares so we swapped them out and kept on truckin'
