Like I said, the N-fabs are more sturdy when talking about stepping on them. My best friend that I mentioned knows for a fact since he's 400 lbs lol. The first time he used the N-fabs after I had them installed he said that they seem more sturdy.
I will admit though that these N-fabs and basically any steps with the drop down hoops seem to be a little lower and stick out a little further than regular 3"+ round or oval steps. Especially being that my truck isn't even leveled. But, I don't go mudding or off-road in this truck like I did in my 98 so I'm not too worried. Especially since as I said before, that I banged them on a concrete curb a couple times and didn't damage them at all, just scuffed up the powdercoat. Also my best friend had one of the pads come off and I won't have that problem with my N-fabs since the stepping pads are metal that's welded to the hoops lol.
I have nothing against tube steps and I'm not the type to tell someone how to spend their money. I'm just glad I tried these N-fabs out because I was about to get 3" tube steps like what was on my 98. I know you said you'll get the AMP steps down the road and I've read that some people think they give pretty good rocker protection. Rather it would be better than hoop steps like my N-fabs, I don't know.
