^^Explain this a little more. Do you have a RotoFlex that has to be locked out, or a conventional Morryde with a rubber shear spring? I don't think the shear spring model needs to be locked out for a Andersen or PullLite hitch. But I may not be understanding what you're saying.
That aside, I would load up and get the pin weight up, get the truck on the overloads, go to a CAT scale, determine if it's still chucking, then get closer to your tire and axle limits, but not over.
Rotoflex - per Andersen they have to be locked out from being able to rotate.
