@AnnaZ We have a campground book that lists campgrounds by area. It is very large and heavy, but in most instances, when you have a choice of places you can go on line and check them out in depth. The books are available at Camping World.
DH has to pull over if he has to use the facilities, but that is an advantage I have being the passenger. I am free to move around as long as we are on the open road and not in heavy traffic.
