Minor problem, but still annoying. Anyone with a 2005 extended cab. Does your right rear jump seat fall down all the time. It has that annoying plastic box on it for extending seat for child safety seat. I believe the weight of that and the metal legs inside are causing to much weight at the top of the fulcrum so to speak. Every time I brake hard or hit a bump the sat folds down. Is this a problem with the springs on seat or a design problem. I may remove the child seat thingy but it will leave those two metal clips exposed that cannot be removed. Any thoughts on this issue???
