So why do the SUTs with tonneau covers have these rubber pieces? </div></BLOCKQUOTE>
Good question. I have a half-baked theory.
In the bottom of the bed are four drain holes that let water out and dirt in. With the cover, that dirt has basically nowhere to go and maybe, just maybe, there's a slight increase in pressure inside the bed while moving, which forces dust back out the drain holes and through the midgate sides if that area isn't covered.
I did notice during our last off-road adventure (while missing the right side rubber flap) the cab had a lot more dust in it. Previous runs (when the rubber piece was in place) there was only a small amount of dust.
All that hallucinating and it's not even 10 a.m.
