I currently have one mounting point for the camera on my trailer, drivers side at the front, for time lapses. The only problem with the GoPro is the battery life. It dies after about 90 minutes of taking pictures, at 10 sec intervals.
I also got a suction mount. Apparently it's rated to 200mp/h, but it still makes me nervous.

I understand what you are saying about the suction mount!
I don't have a Go Pro, but on my motorcycle has some plastic side covers that are only held on my grommets and I have heard of people losing one if the wind gets under it and pops it off. You might not even notice when it happens, and they are rather expensive to replace despite just being plastic!
So as a precaution, I have mine also secured by using thin stainless fishing line leaders as additional tethers.
They are normally hidden inside the plastic covers and serve to tie the covers to the bike's frame. They are long enough to be easy to work with when removing the covers, but short enough that a cover would not drag on the ground if it did pop off the bike.
Maybe you could rig up something similar to use with your suction cup mount for added peace of mind!
