I think the Rand-McNally has a height warning built into it's software and will route around low bridges, etc. I'm not sure, but I don't remember the GS trip planner doing that.
GS Trip Planner has that too. It took me around a low underpass in Pierre, SD on one of the trips we used it to plan.
It also has switches to keep you off toll roads and Interstates if you don't want one of those. The problem is that it assumes all national parks are "toll roads" because they charge an entrance fee. So, you can't stay off toll roads and take direct routes into or through a national park on the same route.
