Ford 350 chassis handling

Harvard I don't have it in front of me but when I had alignment done it was in the plus 4 to 4.5 range with one side somewhere around 4.5. The rig appears level, when weighed without people in it there was 3800 on front and 7300 on back. E450. Tire pressure at 50 PSI front. Next time I go in for alignment I'll request as much caster as they can dial in-it would help on center feel, return to center, and improve tracking. Straight ahead tracking hasn't been biggest concern, my quibbles are with steering non precision tied to roll-something I found significantly improved by Roadmaster Sway bars. Track bar less so but still represented improvement. I think heavier shock valving would help too, but I haven't gone there yet. Again-this all may be something that hits me and could be less for others.
