Leer 100XQ was installed last Friday. First thing I noticed when I opened the cap rear door were the concealed, flat door hinges. Online videos I viewed of the 100XQ showed the "C" hinges, like on the ARE Z2. Those videos were pre-T1 GM trucks. When I closed the cap rear door, I noticed the obvious, Leer has a new mold for these T1 100XQ's, at least this Multi Pro Tailgate model. The top of the cap is no longer smooth all the way across. The contours start at the front of the cap, inline with the two main truck cab contours, and run the full length of this cap to the back. The center section of the cap is lower than the outer sides, height matches much better to the cab/spoiler. The contours run directly over the hinge mount location. That may be why these new 100XQ's have the flat exterior hinges as compared to the previous"C" hinges. Clearance/mounting issues with the "C" style hinges in this contour area.
Overall fit is good, the bottom edges of the cap are smooth, no obvious chips or cracks. Paint color match is also good. Rear door closes okay and it fits the Multi Pro Tailgate.
Ordered this with the Leer plug and play T connector. A thank you to ShamrockShooter for that advice back on page 2, I had no idea that connector was available. No warning messages or other display screen/electrical issues so far, have not tested a trailer connection yet.
I will try to post 2 sets of pics, some with this post showing side and rear view, more on a future post showing views of the cap top shape. First attempt trying to post pics..
