rear bumper

Okay I have an 09 avalanche Z71 package and when I put the tailgate down I have very little room on the side to put my foot does anybody else have this problem to get into the back of your bed does anyone know if I know on the first gen they had the bumper with the footstep in it on the corners...

I'll cut straight to the point. My dad has a 2017 Duramax and it has the coolest bumper I've ever seen on a Silverado. It has pretty much the same concept as the avalanche and I was wondering if anyone has put one on an avi. My truck has no backup camera or sensors. I saw an image on this forum...
