Don, there are several good rv parks in the area. We stayed at Mountain Meadow RV Park at Hungry Horse, MT, and feel it was one of our top two favorite rv parks of all we haver every stayed in. It is a fantastic park. Much like what we had at the Mt. Shasta rally but maybe even more privacy because of the trees. I just checked S&T and we were 9.5 miles from the west glacier gate. There are several other good choices for rv parks, including Timber Wolf, also at Hungry Horse and close to Mountain Meadow.
Don, you will absolutely love Glacier. If you have time, our website will show you some of the off the beaten path places for sightseeing as well as restaurants, etc., and the usual places to see in Glacier.
