Is your deck system water resistant or waterproof (which would make it mostly dust proof as well)@dwl
Most tonneau covers compete for the same real-estate that our rack's mount to. This creates a compatibility issue between our bed racks and most traditional tonneau covers. We have come up with a clever Deck solution.
Otherwise try to find a tonneau that doesn't occupy the top of the bed rails, or one that can be modified to work with our bed rack mounting brackets.
