In viewing all the great TD's on this site, I've noticed almost all of them have wheels covered by fenders and mounted outboard. I've been thinking going inboard (ala the baja benroy) and using some of that extra space for storage and the like. Am I missing an obvious reason as to why the fenders? Is it ease of construction, design factors, stability, or something else? A little help for a relative newb would be appreciated. Thanks!!
