Questions about 5th wheel on Lowered Truck

I'm looking to buy a lowered 98 chevy dually. However, I'm wondering about the 5th wheel hitch. The truck is very low and has helper bags. (the ride does not return to normal height.)

The question is do I raise the tongue to match the trailer or can I lower the trailers receiver? (I am new the adjusting of these parts all I ever do is drive never had to hook or disconnect anything somehow).

Ignoring any weight carrying issues with the truck, I would raise the hitch first to its tallest height, then lower the pinbox to make it level- my reason being the hitch/truck frame combo is stronger usually than the pinbox/trailer frame, and extending the pinbox puts more stress on it.
If the trailer is raised at all, I would lower it as well.
