While we're discussing all these attributes
one thing I learned about this rack/cover combo is that when you open it, you don't want to maintain control of the lid as it opens. Once it gets going, there's a lot of momemtum from the weight of the rack, and the light-duty aluminum piano hinge is not meant to withstand that type of abuse. Not to mention that the tonneau itself is just a very thin-guage skin wrapped around a styrofoam core.
