Got another gadget, the Level Mate Pro. After installing I raised the jacks and releveled the coach, as you can see the auto level is about 4" low on the right side. I used a 36" level on the floor in several places and counter tops, it confirms what the Level Mate is showing. Guess now I need to recalibrate the auto level and see how close it will come each time.
I tried both my old 10" iPad and my wife's 7" iPad, after switching back and forth I'm staying with the 7". The 10" iPad is nice but just to big, takes up a lot of real estate on the dash. The 7" still gives me a nice big picture but doesn't take up as much room and is a lot lighter, like it!
