Hitch Pitch
Just turn it on, connect to your Android device, place the Hitch Pitch on the trailer surface you want to level, use the intuitive App screens to find a level position while backing up your trailer, and finish the trailer leveling with a top overview that indicates which corner to raise or lower...yep it's that simple, and it doesn't have to sit in a drawer until the next camping trip either because it makes a great level too.
