In my case, the shelf was just two lengths of box aluminum held in place with detent pins. I made them for Joe Ayala and he said they were the best thing since sliced bread. Takes less than 10 seconds to install and takes up hardly no room in the van at all.

My Rock And Roller is an R-10 and when fitted with the gear, which consisted of the PSR-S910, Bose L1 Compact and extensions, custom console, gear bag for mics, spares, etc, my folding gig seat, double braced X-stand and Bob The Flame, I still had room for more and the cart never struggled.

My R-10 with the shelf installed, also served as a great setup platform using the inside of my semi-rigid keyboard case as a platform. The case also held the Bose cover and was a good place to store the gear bag. I just wheeled it out of sight while on stage.

Yeah, those were the old days, and I like to think them as the "Good Old Days" because it was just over 2 years ago and everything was smooth as silk.
