Best Leveling Kit For Plow Truck???

I've research'd and research'd and can't decide what to do. Ive got a 2012 f350 CCSB. It's my daily driver, work truck, tow pig, plow truck, etc. i know I'm gonna hear Icon or Carli but are they the right choice to be hanging a heavy plow off of? What about putting together a leveling kit with a set of HD coil springs (like from sdTrucksprings.com) and then buying caster shims, adj track bar, and new shocks separately?

My truck is not a Cadillac and if I don't have to I don't wanna spend $1,500-$2,000 on a leveling kit that will make it ride like one. I also don't really wanna do a puck lift either.

Need some help on this one fellas, thanks...

You can put on the Icon springs with the bilstien shocks to save you a little bit of coin. I am not sure how they will handle the weight of the plow though. Firestone does make air bags you can put in the truck to help with the weight of plows, then you would could carry the load when you need to and have a better ride when its not on there.
