I too am aware of the 11.8 video but feel that threads like this can really help out before any damage can be done! Now in my case my truck camper on the truck did measure at 13.7. That's change now as I have a new satellite antenna that I would say is about 6 inches taller. I need to take another measurement but I also do not have a latter on the TC making it difficult. Below are some images of my TC.

Hope the images come through. It's been a while since I last tried this. :)
