I don't recall where I was told or read that there was a difference between the cargo and passenger van gaskets that came from the factory.
I do know that when I taped a secondary row of insulation about 1 or 2 inches behind the factory gasket, I did not have a dust issue with the rear door. I installed the tape several feet up the sides of the door jam. The factory gasket is still in good condition, but it never sealed completely so I just added a secondary line of defense.
