I have the Pelican 1535Air, which appears to have the same dimensions as this one, and I was able to add the 1519 Lid Organizer without any problem. The back of the organizer is just (stiff) cardboard, so all you have to do is poke 4 holes in it to screw the organizer to the underside of the lid -- at least that's what I did and it worked fine. I don't see where adding the organizer to this model would be any different. If the organizer is too wide (as was suggested) -- again, it's only cardboard, so you should be able to trim it a bit if necessary.
