I had driven a short section of the river bed and wanted to go back and drive the river bed as far as I could go. Locals all told me that I would damage my FJ and that it was not wise. Too difficult they said. There were lots of river crossings which ranged from shallow to 600mm and there are river rock, but if you choose the right line it should be fine. I have a 2" lift and under body protection plates and I never dinged on the whole trip. Mark with his 80 Series joined me for the challenge.
