Check the black vent cover on top of your T@b (above the air conditioner)

We've lost 2 vent covers this summer, and we think it was due to the position of the screw when it was installed. 

Our original vent had the bottom part installed so that the screw was toward the rear of the T@b. While traveling, the wind would lift the front of the cover and this resulted in the plastic tube snapping off (this tube is where the screw held the vent cover to the bottom part). Ed sent us a new vent and we installed this one so that the screw is toward the front of the T@B. Now, the wind created by driving at highway speeds shouldn't lift the vent cover anymore. We hope.
