I was clipped in a gas station by a semi last night and the pipe and some of the coroplast was broken last night. It had to be removed, so for the next 3000 or so miles, back to stock unless I get some time tomorrow.

The bottom was flush with the bottom of the trailer, but the top was not as to allow the hinges to fit there. Again quick and dirty. I also didn't want to cover the upper marker lights.

I encountered a problem that you may know about. When the boat tail (or whatever its should be called) was installed, when a vehicle passed by, or I passed a vehicle, the truck would be pushed slightly towards the passing vehicle. After it was removed, that didn't happen.

By the way, the sides of the unit were pulled lightly in towards each other. Its probably hard to see from just the one picture.

So, if I did get a chance tomorrow to put another one together, how should I make it? Flush with the top, flush with the bottom? More of a point? It was about 36" from the trailer and I did pick up some LED tail/turn signals to be legal.

Thanks,
I will try and check back later tonight.

The pulling together is the airflow rushing between the trailers creating a vacuum.
This sounds crazy but, dont fight it. Let them pull together and they will seperate when the pass is complete.
fighting it will lead to sway and a potential comming together as the air flow destabilizes.

9MPG -12MPG ?
You should be getting better than that, although you are going 75MPH.
I get 12-14 with that thing V
