I am planing a trip from Ohio to the Mount Rushmore area to West Glacier to West Yellowstone to Jackson, WY to Breckenridge, CO the end of August 2017 through September 2017. I have planned out the routing but am concerned which roads are suitable for our 36 ft class A motor home with a tow. Specifically, MT 3, 12, 87, 89 (between Billings and Great Falls), MT 89, 2 (between Great Falls and West Glacier), MT 35, 93 (between West Glacier and I-90), MT 287 (between I-90 and West Yellowstone and WY 191 (between Jackson and I-80), WY 789 (between I-80 and the CO border) and CO 13, 40, 9 (between the CO border and I-70). Any info/help would be greatly appreciated!!
