The 2500 places the suspension too far inboard resulting in sway with top-heavy loads. Add Sumo Springs or Timbrens outboard of the airbags and install the thickest stabilizer bar you can find for your truck.
I have done it both ways. I started with a truck bought for another purpose that had a strong foundation for upgrades and figured out the parts to make it happen. I wanted to up-size campers to something beyond what that truck could handle OEM or upgraded, so I sold it and bought a truck that could handle the load in OEM trim knowing I could modify it later if needs changed. There is usually is more than one way to handle issues and many times the right way for someone is what you feel is the most comfortable even if there there are other paths you could have followed.Or do something really different. . .
Just buy the right truck for your specific camper in the first place. 🙄
