leveler landing pad hits leaf spring
MH is a Fleetwood on an F-53 Ford chassis. The front leveler cylinders are mounted in such a way that the landing pad is slightly (maybe an inch) under the leaf spring. At times, usually at slow speed...

I don't recall Ford ever included air bags on the F53 chassis or any coach builder adding them. As such the bags were installed by an owner sometime in the rig's life. With the bags inflated I suspect they are raising the frame/jack higher and closer to the leaf and tire. You could try dumping air pressure and try and duplicate conditions.
To correct the jack needs to be repositioned low, at least as much as the bags raise the chassis. I installed the jacks on my coach and I have air bags but my front jacks are well clear of the front suspension components. I'm pretty sure in the installation instructions for my jacks the recommended height of the pad at 7 to 8 inches when fully retracted and above the front axle. Drop the jacks as low as possible but stay above 7 inches or at least the level when the bags are deflated.
