I doubt you'll find many trails between Michigan and Texas. A number of years ago, however, I rode a bicycle from south Texas to Michigan (See my book, NORTH BY BIKE). I smaller. less traveled roads all of which were bicycle friendly. I camped most of the way and had little problem finding a suitable campground at the end of each day. I just bought a 2010 TW and I wouldn't hesitate to ride it from Michigan generally following the route I took on my bicycle. Good luck!
