I don't use it much and put it in over the weekend. All looked good until I tried to take it out. Apparently the cargo area floor mat is under one of the three rear clevises, between the clevis and the rod. The other two clevises are clamped, the third appears closed. Neither lever one nor lever two will operate. If I pull up on the seat lever one moves a little, but seat back only rocks forward a little. The carpet won't pull out. Is there a way to manually disengage this without using the levers? Is there a way to trick it? HELP!!! I need my load bed back!.
