I received the cargo bag today. Decided on this vs making some type of a glove box. After test mounting to the rear, upper cross-member, was not happy that it was below the hardtop and partially blocking the rear view. I think I found a solution though. It appears that I can easily make my own cross-member from 1" PVC pipe. The ends would be captured at the gap between the 90 degree bend of the roll cage and the hard top. I will have to release the two rear hardtop clamps and tilt the top to get the PVC pipe in, but that should be easy and will not require any permanent mounting holes, etc. I should be able to pick up the PVC tomorrow, and give it a shot. I'll post results with pictures.
PS: Still cold here but the P500 is covered with spring mud already.
