That length is for the Highway to the Sun road, which is extremely curvey and steep. Don't know about the campgrounds, but if you can't get to them without going on that road, might be a problem.

Not really, the Going to the Sun Road restrictions are 21 feet long by 10 feet high by eight feet wide. The OP is correct that most campgrounds have a 35' limit listed though St Mary does have three 40 foot sites.

I camped at St Mary CG in a 33 foot TT so I am longer than you. I had problems getting into the site assigned on the B loop but made it. I was in a 35 foot site. The pull through are wide spots on the side of the campground road with low wooden post and low brush to prevent you from driving off the assigned site "road". No room to "swing wide" and pull in. At my site the length was not the problem. The swing wide and the "tail swing" was the problem.

There were a number of big rigs MH camped on the upper C loop with no problems.

On my next trip, I am planning on staying at the Canada Waterton Lakes National Park downtown campground with full hookups and a Very nice park. Maybe better views and overall better NP that USA Glacier NP. It may cost a few $ more, but I will try it. I will do a day trip to USA Glacier and drive the Going to Sun road in my TV.

Be aware, this year 2017 Canada does not charge any park entry fees so expect larger than normal crowds.
