Hello Mozza,

I have a pelicase mounted on a TT QR mount on the yamaha rack as a top box.
I have a powerlet charging set up in it for the lap top and the camera and lense fits in the foam beside it. Only use a Nikon 18/200vr for every thing.

When i need quick access when on the bike the camera goes in the Famsa tank bag. All works well for me.

Hope that helps
