right now not good travel weather on any of the northern back roads. 191 is sometime shutdown due to snow and it is/was not maintained from hannigan meadow south dont know if that has changed.
191 from 40 going south is rough as a cobb and not much fun besides there is nothing but miles and miles of nothing if looking for scenery. I also think that there is a length limit on 191 out of alpine and personally would not try to take a TT/5w either direction on it (doubt if I would in a rv either). its approx 115 miles from springerville to clifton, took over 4 hrs when I did it in a pu with cabover camper, did it on a motorcycle in much less time. Do your homework before attempting.
