Installed the Maximus 3 side ladder onto my Rhino Rack with Backbone. Technically, it's only designed for the Maximus system, and even though there system uses the Rhino Rack Platform, the Platform sits in a different position height wise, so the ladder isn't sold to work on the Rhino's with Backbone.
Ended up making some small spacers to take up the height difference, and drilled my holes in the tub of the Jeep in a slightly different position to put the ladder closer towards my rear door. My point for running the ladder is so I don't have to carry the telescoping ladder for the RTT any longer. Less stuff inside. I think it turned out pretty well, and it gets the job done!
