Just bought a Husky liner for my 2005 with DD. The liner fully covers the cargo area with the DD down. It would hang over the end of the shelf with with DD raised. I don't use the DD, so no big deal. Because the website doesn't explain this clearly, I called Husky before I bought- basically their liners are custom designed to cover the entire cargo area- DD (down), no DD, or 3rd row seat- just buy the one for your configuration...
