Level Kit Or Lift Kit? 2nd Gen

Ok here's my story. This is for the truck in the sig.



I trying to figure out if i need level or lift and how much? I wanna run 35" tires or equivalant no wider than 12. 5. I want to run them on 3rd gen wheels which dont have much backspacing/offset. Down the road i will get aftermarket wheels but gonna use these 3rd gen wheels since they a freebee. I don't want to have them close or have to trim much of anything if i dont have too. So basically i'm wanting whats gonna be easiest to just throw them on and not have to worry about rubbing or anything like that. . I also plan on rubber flaps all the way round but they are real thin and wont pose a problem.



So do i level it and have enough clearance or lift it?



THANKS
