First thing is to make sure the ride height is correct. About 12" both behind the front wheels and in front of the drive wheels as you already know. I rub at the slightest incline. I've learned to raise my coach when in doubt. When Newell works on my coach and they carry it to the bays on other side from where we park overnight, it rubs going into the bay. I ask them to raise the coach because they messed up one of the snaps on my break-a-way hooks the last time I was there. When they backed out it did not rub. Tom I really can't tell you how much incline, but I can tell you to make it as small and long as you possible can. From the looks of your property it looks fairly level.
