It really depends on your end goal. Are you going to autocross the truck? Track day/road course? Just want good street handling?

I've built many cars for autocross and road courses, including a 2003 Ford Lightning Pickup that would mop the course with most cars.

You need a good balance between rigidity and body roll. If you eliminate all body roll you will skid right off the track. You need the additional traction on the outer wheels to carve through an apex. Also, low profile tires are bad for the same reason, you need the deflection. Tubular a-arms help prevent deflection during hard cornering.

Large sway bars aren't any good without a balance. You have to match the sway bars to each other and to the truck supension to achieve the desired understeer/oversteer ratio. Typically, you want to tune the suspension/sway bars so you have very minor understeer versus oversteer until you get use to the truck. Your camber setting will also greatly influence this as you dive into a corner your camber will determine how you track out of the corner..

Independent rear suspension or at least a 4 bar configuration is the best way to go so you keep as much of the tire on the ground as possible. I could go on for hours on this topic but I think you get the general idea. If you have specific questions let me know.
