Okay Peter here is what you need to realize. Life isn't all about size. Your friends wont laugh at you if you don't have 40 inch tall tires. If you move down to a 35 or 37 inch tire and some Chevy 63"s in the rear and the rears up front with a custom pack you will have much better flex. Ask someone with this setup what is in their custom pack and how happy they are with it. I have heard you can get 5" of lift with this setup, but the Chevy springs are rock hangers, not that it really matters in the mud.
