Having just purchased my first RV im worried about on road parking as the door opens out onto the road and me and my doggie have a habit of just jumping out. Ive looked on the Highways code website and it states that you must park in the direction of traffic at night unless in a parking bay, though if the speed is more than 30 MPH parking lights must be left on ....doenst this flaten your battery ? I wondered what experiences other RV'ers have had ????
