I'm taking a wild guess, but that looks like a 305mm width tire or maybe even 12.5". It looks like the BFG AT's 305/75/16.
Anyways, I reccomend the 5" Tuff Country lift kit. It's super strong and well put together kit. The kit itself will run you about $1500-1600 depending on where you buy it from. Plus since you have a 2wd truck, then you won't need to cut the front crossmember ti install the Tuff Country drop down bracket. So that gives you the option of removing the lift kit if you ever feel like doing that....which I doubt.
The 5" kit will easily let you run a 33" tire like the truck you posted up. You might want to think about regearing when going up to this tire size cause you will feel a lost in power and your MPG will go down just a bit. New gears like 4.56's will give you back your power and MPG's.
