I needed to cut a hole in the bed cover of my truck to fit a bed mounted Crain.
I needed a way to stop water getting into the bed but that allowed the Crain Poast to stick up out of the bed.
so i made a basic funnel with a slant to catch and re distribute any water through a drain hole via rubber hose to outside the bed.
pictures do not include hose attachment.
