If you look at how Nerf bars mount, they won't provide much of any protection against trail damage. You will just end up with a expensive bent-up side step.
These are from my 4th gen, I assume the 5th gen is no different. It's just 3 dinky mounting points. Take a look underneath and confirm it yourself.
Personally I didn't want anything other than real sliders... it wasn't worth it for me to spend the money and not get the protection. I've seen my friends use them for pretty aggressive things including hi-lift jacking up the entire truck from a slider which is a selling point for me.
I don't have any complaints with ground clearance. Didn't want steps that protrude down which hinder ground clearance either. They do sit up noticeably higher than the OEM steps.
I bolted mine on first, then welded it after I was 100% sure I liked it. I could never see myself taking them off, they already paid for themselves.
Went with Demello Offroad... so far so good. Very stout / beefy piece of kit.
Sometimes I wish it had a kick-out, but only when really getting into some rocky situations. I really don't like the way kick-outs look, but they have a purpose.
Photos before welding (bolt on only) and well used.
They angle up a bit which I like a lot, really tucks into the rocker panels.
Not trying to sell you on something Demello, but the one time you come down on something and damage your truck, you will regret the decision to go with a Nerf bar.
If you know you will never off-road, then really, it doesn't matter. Just don't assume a Nerf bar will provide any protection. They look aggressive, but don't do much over the factory OEM running boards.
