RE: Horizontel stab dihedral
The Autoland on the L-1011 crabbed the plane relative to the localizer beam, pointing the nose into the wind.
At 5 feet, the rudder pushes the nose to align with the runway heading (decrab), so there's no large lateral forces on the landing gear.
I watched a DC-10 look like it was going to tear the gear off, landing crabbed at Plant 42, years back.
