Yup, the reflection is a small concern ... but my tahoe oval boards were chrome at that angle and it wasn't a noticeable issue.
I think you're just barely missing my point. You had the TOP of your chrome tube steps reflecting such that it was obvious they were chrome (all around). But then chrome is reflecting a dirty, dark road surface, that piece might as well be black, or BRUSHED, since the image you would see in it if it were chrome would be the road. You're looking down on it, and the sun is always above it, and the angle of it is downward, so it's never going to reflect light like the rest of the chrome on the truck. I think it's currently brushed because 1) it would look brushed in no time with the beating it would take, and 2) because it would only reflect surfaces that wouldn't make it shine like chrome anyway.
if the road were green, that piece would look green, and all the time. With it being brushed, and not fully reflecting the road, you get the impression that it is a trim piece (it's not black), but it also doesn't get lost by reflecting the road surface. So, again, I think it serves its purpose best by being what it is now.
Personally, I always thought that piece WAS chrome, which points to my point even more. By trying to make that piece chrome, or by trying to match wheels to it now, I think you're giving way too much attention to the fact that it's not chrome.
