SO here is the Dealie.
Most know of the 1/4 inch of squeeky space there is to get the lift gate past the high lift.

The 3 dollar answer hangs in an auto store near you. I went to advanced auto and bought some door trim. Little thin black piece of plastic to protect the edge of the door!! I applied the strip to the affected side of the lift gate. There is still enough breathing room AND the probability of dinging up that side of the lift gate is greatly reduced.

Enjoy!
