Several blogs for newbies suggest having a dry erase board in your RV to note important information you might forget, especially in an emergency situation (like where you are.) This seemed like great advice, having been a 9-1-1 operator who has been on the other end of panicked "I-don't-know-where-I-am" phone calls, so I mounted a board with Velcro on the back of the closet door. As I eyeballed it for level, I realized - heck, I'll be living inside one gigantic white board & wondered (too afraid to try it myself) if anyone has written with a Dry Erase Marker on their walls & if so, did it erase?
