Help removing a Kwikee cargo tray - FIXED

We just purchased a Dometic freezer for our rip to Alaska. It will not fit in the short cargo tray so I would like to remove the tray and keep the rails/brackets that the tray rides on. I can't figure out how to easily remove the tray without removing every thing.

Does anyone having any insights on how to do this?

There is a "C" clip on the rear most roller that has to be removed. That allows removal of what I'll call the stopping roller. Once the roller is removed, lift up on the fron of the tray and it comes right out.
