For anyone buying or selling a GFC Topper or Camper. NAPA sells a seal the works great I have used this seal twice, once while moving to a different truck and when I bought the camper. I have always ordered it for store pickup at a local Napa and it has always shown up within 24 hours which I would guess in most cases would be a lot quicker than shipping from GFC. It comes 22 foot in length and has been enough to do a 6.4 foot ram bed on all 3 sides.
