I've been using the Trip Planner to plan our summer travel and I think it's not too bad. My only gripes are:
1. Some RV Parks don't show up unless I use their street address. For example the St. Louis/Historic Route 66 KOA won't show up but if you add the address it magically appears. Appears to be some kind of database query problem.
2. The dragging of waypoints to a different route doesn't seem to work anymore.
3. I agree that the RV Park ratings don't seem to relate to reality. Maybe they pay Marcus to bump the ratings up.
4. I wish they'd eliminate the 25 waypoint limit so I can plan out the whole trip without having to resort to breaking it up into segments. I plan looong trips.
