all three tailights failing, fuse is good, what would cause all three to go out at once?
Try the fuse first.
Water may have gotten into the assembly (not likely but possible). Wiring under the rear of the truck could have been hit by a rock or something. Also check in the same area under the bed by the bumper... a plug/connector may have come loose.

Changing professions or purchasing a service truck so I can make this one all about fun!
I kept on blowing my taillight fuse for several months. Couldn't figure out what was going on. Finally my taillights went out completely. Brake lights worked fine. No other problems.
Dealer found that the wiring harness that exits the cab just below the drivers seat was rubbing against the frame. The wires were finally exposed shorting my fuse and they eventually cut through. They re-connected all wires, taped and then shrink wrapped the harness.
I have a 06 DB and a friend of mine had the same problem with his 05. Not sure if you have the same thing going on.
