I am glad you found what you were looking for. When I told the dealer my plans for the truck they said nothing about the inability to put a canopy on the bed. After calling them and talking with them it seems they had never heard that was an issue. Why would I think that this bed would be different than any other bed in the world. I would think that there should be a way for a canopy to be attached to the bed or they tell you that? I know that its an after market addition but its not a foreign one lots of people put canopies on.
