I'm currently at a campground in Myrtle Beach. While enroute, I had my Garmin GPS set to Motorhome - it tried to take me around the 2 tunnels in Virginia on interstate 77, which would have added an hour to my trip. I ignored the GPS, but as I approached each tunnel I got repeated warnings in red on the screen indicating that propane was prohibited in the tunnels. I know that you are supposed to turn the tanks off while going through them, but never have.
