Let me know if you find a better solution. I am getting ready for next weekend at which time I will apply a sheet of plastic 4 mil and a piece of cardboard after it to the space between the bed and cab. I will then support it with some towels stuffed between the cardboard and the cab to hold it in place then spray foam the area from inside. Will have to shoot the foam in through a couple holes still in the spray in bed liner but should give me plenty of space to spray. After sitting over night I will remove these and hope for the best. Will get color match paint at auto store to paint the foam between the bed and cab for whatever shows. Tghe plastic and cardboard should greatly limit the area it travels to but one dry it can be shaved off before painting. A 1200.00 bed cover and still my tools in truck bed get drinched due to these holes. One at the corner on both sides of the bed. Rediculous.
