After much debate, I ended up going with zone 4.5", fox 2.0's, 35x12.50r20 Nitto ridge grapplers and my stock evevation rims. I have zero rubbing, but haven't had it off-road much yet. The truck rides as good or better as did stock and tracks like an arrow, even at interstate speeds. As much as I hunt from the truck, I wanted it usable. I'm in and out of the rear multiple times with the hawks/beagles and didn't want to be standing on my tiptoes while doing it.
Having said that, if I decide I want the 6.5" down the road , it sounds like all I'll need to do is replace my rear blocks and the front strut spacer and call it a day. The 4.5" is plenty high, I'm 6' and it takes a little jump up into the truck. The truck is dirty, but I snapped a few pics to give an idea if anyone is thinking of going this route.
