Post maiden voyage, deciding on modifications?

I guess IMO, on my old application, overloads aren't doing much unless fully engaged with the bump stops on my old 2002 F250 Camper Package, about 4k + in the bed. When my overloads were squished into my torklift bumps, I was steady freddy. With them barely making contact or with the energies, I swayed side to side. Again, my experience, my 4k weight, my F250 with overloads.
