Thanks for the reply. Sorry if my post was confusing. I have both bags at the moment. The last picture shows the ipad on DXP trunkbag. It is bigger than expected, but I am sure that I will appreciate the space when I drive to the gym.Just post the dimensions of the iPad Air and I will check my MTX DXP trunkbag. I carry an Eagle Creek Pack-it Folder with my clean clothes for the week, it is 12" x 18" and about 4" of it sticks out of the top.
I like your idea with the bolt.
