5th Wheel Leveling

[TheTynman]

I have a new 5th wheel with a 6 point leveling system. When I recently returned from a camping trip, I backed the unit into my driveway (where it has been before). When I hit the "Auto-Level" button, the trailer leveled itself but in doing so, the tires on one side left the ground. Never having experienced this before, I lowered that side until the tires came in contact with the ground. That of course means that the trailer is no longer level. Not a big deal in my driveway but would be a bigger concern if I was camping.
Has anyone had that happen to them? If so, what did you do about it? I'm assuming all 4 tires should be an the ground when camping, right?

Thanks,
Norm
