By 'chucking' do we mean the feeling of being slightly pulled back and forth? I don't have any clunking at all, and no noise from the hitch.
So I looked closer at my pin box and it's a Lippert Road Armor which has a sizable rubber plate between the king pin and the hitch. I don't think there is any gap or looseness between the hitch collars and the king pin, it looks very snug.
I looked at the Morryde pin box and it's very light compared to the Trailair! 32# vs 148# shipping weight. I don't think I would gain much from the Morryde.
Now I'm thinking I should start with air bags and see if that smooths out the ride.
Actually I feel like I shouldn't be complaining at all because it's not that bad.
