Back and forth with Rand over the past week or so via email support. They went from "it should avoid the parkways" to "we dont have enough information to answer your question".
RV Wizard, though a pain to get into Maps seems to work well.
Downloaded the Co Pilot app this morning. Going to bring the rig to Camping World this week. I will try the app then but it seems to be able to do what Garmin and Rand can't.
