Planning our 2018 trip out west to Glacier. Looking for input and ideas from anyone who has been there. Plan to stay in Columbia Falls on the west side of park. Traveling from TN so this will be a 2000 mile trip each way. Glacier has been on my bucket list and I think I'm gonna get there. What can I expect as far as terrain in Montana? Steep mountains and grades? Must see places to see? Last year we went to Colorado and my truck and trailer pulled fine so I'm hoping for the same this year.
