Truck and fifth wheel hitch question

[Bob Dan]

I purchased a 2021 Chevy High Country Diesel 4x4 2500 pickup and looking to haul a half ton 278BH fifth wheel. Any issues with truck bed clearance and getting fifth wheel level? I am reading that some people are modifying there truck suspension or fifth Wheel suspension for proper fit. Anyone have the same set up?

We have the Solitude 310. The only thing I did was add timbrens.

The truck and fifth ride level and comfortable.
