So I have a plan, but I could use some advice. I have a Yamaha FJR, a sport touring bike with hard luggage. On the back is a top box. Here is what the inside of the top box looks like. I checked, and the P3 will fit in there. But now it needs to be secured somehow. My thinking is a foam insert I could slide in there. I have the DJI backpack and I could use that over my gear if I had to. But it is one more thing I have to carry around. The top box is lockable and is also removable if I needed to bring it anywhere. Looking for the best way to leave it in there, while having it secured from bouncing around. Advice is welcome.
