RAM mount from within a truck

I find those RAM mounts very versatile. A bike, a monopod, the roof of my car. There usually is a solution.

But they are not so handy to mount. I have to stick with my means of transport because unmounting and mounting them takes a bit of time. Certainly when there is a second mount with a smartphone.

I’d like to see the Gopro solutions.

Interesting set up. Thanks
