I realized I needed to modify my GT trailer to fit the new GT. First, I needed the base almost 3" wider, and second, because the door is further forward and hinges upward, my trailer side door had to change. I ended up with linear bearings on the roof and having the side door slide rearward. Originally the trailer door would have prevented me from exiting the car after loading. With the window down. the GT door opens fully now. I added access doors at each corner to ease strapping the car down. I also added three line lasers to the trailer ceiling to use as a guide when driving on. I just keep it between the two stripes on my car. As you can see, it's a close fit!
