Am in the design stages of a truggy project to be. Have most of the drivetrain, some of the steel, and all of the headaches staring me in the face and still can't decide exactly how big to make this dang thing. It'll be used for rockcrawling on slickrock and in wash bottoms with boulders. Mostly in Southern Utah but may venture out if successful. I've seen everything from Jon Bundrants "Tiny" to "The Ogre" with its 50" tires. Don't want to be that big or that small. A lot of folks think the 105" wheelbase is the magic number but that seems a bit long compared to my 40. Any input? Any suggestions?
