Suspension.. What is the best on road?

I ended up putting ICON coilovers on the front. Sine my truck is street driven lol. They do seem to have a nicer feel. I haven't changed the rear yet and may be doing that in the future as well as it feels really stiff back there.

 

Absolutely not overkill if you have the money. Fox adjustable suspension would give you the ability to have a great ride on road and great soaking up of bumps no matter what wheel size you have or what load is in the truck, provided you do a little tuning and get them dialed in or have somebody with lots of suspension tuning experience do it for you. Also you could obviously run it offroad if you wanted. I have Fox 2.5 Coilovers and DSCs on my truck and have only really driven it on the street so far and love the enhanced feel and responsive steering. Don't cheap out on UCAs though do those too while you're in there as they will help with handling on the road quite a bit as far as tracking straight and avoiding groove hunting and things like that.

 

For a no budget, absolute best on the road type build you would want to do a traction bar mounted dual shock setup with an internal bypass and external bypass in the rear, and a coilover and a bypass shock up front with a dual shock setup. That would be the best ride for crap roads you could ever get with more than enough bump dampening to take anything a road could dish out including pot holes and speed bumps.

To put it simply, bump dampening in this case works a little like how much money you have, as in you can never have too much and even if you're comfortable right now, more dampening being available would never be a "bad" thing (provided your shocks are tuned to be soft enough so that they don't affect the normal ride). This setup would allow you to easily switch between track days, to driving around on the street, to taking jumps on sand dunes, to just about anything you could imagine putting a truck through. Not only that but once installed all these parts should be good for at least their 50,000 mile rating but probably more since none of them would be stressed in the slightest bit keeping your truck planted on the road and keeping you comfy.
