I have done 191 in a 30'MH with a 16' trailer in tow its a slow drive to Hannigan Meadow but a great drive if your not in a hurry. The tunnel is no problem 20-30 acid tankers go thru it every day. Drive up 191 to Alpine eat lunch come back on 180 thru Glenwood NM its 2 miles longer than 191. When you go past the RR depot in Clifton take a left couple blocks farther on Chase Creek and see the old turn of the century buildings watch close for big horn sheep from Clifton to past the mine 1-2 get hit quite regularly.Your in my back yard and we drive this 4-5 times a year go slow and enjoy.
