Sounds like your trip planner had there training from CAA trip ticket people. We stopped using there services years ago. Now we do trip planning with Microsoft Streets and Trips, You can select the highway types to use or avoid. You can also 'drag' the route to different areas or roads. Unfortunately, I don't know if campgrounds are listed, we usually just wing it.
We also use GPS (Garmin), with intermediate points setup.
