Always refer to the manual that came with the tonneau cover for proper tonneau cover maintenance, weight ratings, and if it is absolutely necessary to stack items, spread them out as evenly as possible.” If you have additional questions, reach out to the manufacturer where you purchased your cover, for advice.
