you do not show, and I do not know why you don't, how the front bar attaches to truck roof. All that is said is it is universal but I want to know how attaches
You will just place the block legs of the crossbar on your roof and then run the strap inside your vehicle from one side of the crossbar to the other. We don't have an installation video of this but you can find the crossbar as part # DTA968 along with plenty of pictures that others have sent in.
@JonG if I understand correctly the strap will crush the doors weather stripping. i will have to rethink this. Probably a good thing that you do not show that on a video
@MikeS Something as soft and flexible as the strap will not damage the weather stripping. Maybe if you left it on for weeks or months at a time it will eventually warp the weather stripping a little but it shouldn't be doing this under normal use. If you can let me know what the year/make/model is of your vehicle I can see if we have a custom fit single crossbar system that you can install instead of this universal system.
