Got a Snug Lid SL on your 2nd Gen?

I do and I'm curious if anyone has come up with a solution to close the 1" gap
between the rear seal of the cover and the tailgate cap.

Every time I hit the desert, my gear in the bed is COVERED in dust.
Lousy design flaw and am waiting for a response from Snugtop.
Thought the dust was coming in between the tailgate/bed jam until I noticed
the gape between the cover/tailgate and the dust on the seal.

In the meantime I was wondering if anyone has added some sort of tailgate
cap to makeup for that 1" difference between the side bed rails and tailgate.
Seems like the easiest solution, but I haven't found one that adds an extra 1".

Any 2¢ is greatly appreciated!
