Hello All !  Just heard about this forum and wanted to check it out.  Recently bought a used Motorhome and am going through a learning curve on many of the sub systems.  Making our first long trip from Florida to Virginia in three weeks.  Hoping to stay on Interstate roads until I get more knowledgeable on road networks and overhead height clearances. Bought a Garmin RV 890 off of eBay but don’t have it yet.  Should have it before next trip.
