GPS specific for RV's

CoPilot app is made for IOS and Android. For ten dollars it does everything the standalone GPS units do and has RV Mode for routing around low clearances and propane restricted roads, bridges, and tunnels. Lifetime free maps. No need for a data connection as all maps are stored on the phone or tablet's memory. There is traffic routing which does require a data connection (uses very little data) and this is free the first year and costs $10 a year after that by subscription.
