1/4 inch per foot is standard for driveways. Like some others have said, where you park your Coach you should be level at the wheels. So you do not have to have the front end up 10 inches or so to be level. There are many ways to do this, draining to the sides is just one.
Check with some of the luxury RV resorts , their pads are almost level at the wheels.
