I have an app on the iPhone and iPad (Allstays) that I really like for route planning. It doesn't do any trip planning but for me is a very useful tool for locating CGs (Wal-Marts too), fuel stops, low clearances and RV parts houses. Figure how many miles you want to log for the day and look for a CG in the area. Same for the destination, if you don't have a CG in mind search the area for a suitable one. It also provides links to CG websites. I find it very handy.
