suspenion upgrades for 1/2 ton?

[chris mc bride]

Going to have to beef the suspenion on my 69 1/2 ton panel up some for towing my Front Engine Dragster to races most less than 100 miles from house.For long trips I will use the Fl70 based motorhome we built few years ago.Love the panel with the old school dragster but hard to argue with 900 ft lb torque,sleeping in full size bed,heat,ac,stove ,fridge and full size shower.

Trialer I am planning on will be 28 or 32 footer all aluminum construction,weel excapt cpl frame and toungue pieces. Car only 1600 with my 230 lb butt in it. Good amount of spare stuff though.

I need know whats best suspenion upgrades and any thing to stiffen frame on the panle.Thinking boxing the frame will add good amount to it.Maybe over ride springs, and of coarse load equalizer hitch. Any more ideas are welcomed.
