Thought I'd figure out how the hitch on my 1 week old 100D works. Kinda frustrating since my delivery specialist had no clue so she called up a service tech. He proceeded to give me directions...which landed up being completely incorrect. He literally told me to just push it up there and use the wheel to unlock it. Nope. Thank you Google for showing me the real way. Anyway...I popped on our massive Thule T2 Pro with extension. This is a huge 4 bike rack that is very heavy. All looks good though. I don't think I'd fully load it up...too worried about the weight. But I'd feel ok putting 2 bikes on it. I have a Yakima Dr. Tray on order for the Model X. Will likely leave the T2 for our other SUV. Just thought I'd post pics in case anyone was curious.
