It amazes me how large four wheel drive vehicles can crawl over obstacles when given enough ground clearance and traction!! I had spend the night on a solo hunting trip for the last few days of deer season in Lockwood Valley, CA. Trying to cover as much ground as possible to see the local terrain, having a four wheel drive truck with low gearing really came in handy! As the video shows, climbing up over rocks and ruts that would be difficult even on foot, came naturally and with ease for my Diesel-Veggie Oil Suburban!! I actually got out of the truck and walked the route down to the bottom and had to be cautious with my step and foot placement.  For those of you who get motion sickness with videos easily, be forewarned!!
