There actually isnt much it would really need. I believe the turning is operated by applying the brakes on one set of tracks, so turning and braking is already covered. Basically ditching the dump bed, its components, put a seat on. Then move/build the controls. No turning mechanism needed as the brakes are the turning. The big thing would be a CVT to increase the speed. The Offroading spot by me is basically all mud and (lots of moubtains) in the winter, so that could be fun. Put a snorkel on too, haha. Here is a pic of the actual model....
