Nice work!

On mine I came off the steel bumper with a support frame (serves a similar purpose as your trailer hitch). But that alone is just a support for the weight. I clamped rods (with vinyl tubing over them) across the trunk lid to actually keep the thing in one place. It is strong, you can push on it and it solidly moves the whole car around.

I left my existing sidemarkers exposed, you can just see them directly from the rear. Also you can see the factory taillights through the window if you are up high enough.

One thing I did notice when I put that extension on the tail (which had the taillights closer together) is that a lot of people wouldn't get into their own lane when passing. I thought perhaps it was because my car might have appeared narrower. But then again, you're supposed to go fully into the other lane when passing, regardless of vehicle width. You don't crowd a motorcyclist out of his own lane just because he has a narrow vehicle.
