While I am not a fan of the running boards, I'm going to go against the general consensus and say that I think the lines of the truck look off without sliders or running boards with the stock bumper.
It's that lower plastic valance on the front bumper that throws me off, the way it hangs down lower than the body. So I say either go with an aftermarket front bumper, sliders, or both. And get some mud guards for the front or you'll be spraying shit everywhere you don't want it to be. I will write a note to give to your wife that states that these components are necessary for your vehicle to operate.
Just sayin
