I was there this summer. I would recommend going into the park from the west entrance. Lots more around the area.
If you halve to go to St Mary's I would look at 464 but it is a lot further. Never try to tow on HWY 49. After driving it in my CR-V I wouldn't drive it again. 89 starts out not to bad but the last 10+ miles you can see the back of your rig on some curves. I stayed at Glacier Meadow RV Park 15735 US-2, Essex, MT 59916, glaciermeadowrvpark.com, (406) 226-4479, while we explored the east side of the park and at Glacier Peaks Mini Storage (yes it realey is a rv park)
3185 MT-40, Columbia Falls, MT 59912, glacierpeaksrvpark.com, (406) 892-2133,
while we spent a week on the west side.
