I do not see a problem with driving your coach through the park. There are no tight turns. With that said there are no shoulders to pull off on and if you decide to stop some of the overlooks will be tight. The roads are wide enough that it will not stress you out but one cannot let it drift off the side of the road. If you are going out the west gate you must be heading to the west side of Glacier. It would be somewhat longer but I would head out the east gate and spend a night in Cody. From there you can take your toad on an easy days drive on the Beartooth Parkway. It is a must see and might be some of the prettiest scenery that you will see on your trip. If you choose to you could come in that way from South Dakota. You will enjoy Colteer Bay. The restaurant and grocery store there are pretty nice.
