Normal
It could be a custom cover that someone built. I'm not familiar with the logo. I noticed there's some scuffing on the tonneau rail where the rack meets it, so that might mean modifying it to make the two work. I imagine that an inside mounted cover will fit, but there will be gaps that would have to be filled, or the rails would have to be cut around the rack's uprights. Still tricky either way, because that could mean leaking.
