Wound up adding this to the bed. Was looking for something to stop my golf clubs and groceries from always sliding to the front. We already have those accessory rails in the bed if you added the bed utility group. The part number is, Cargo Bed Divider - Mopar (82215481). Couldn’t find a definitive answer if it would work with the factory trifold. Works just fine, have to use the latches at the right angle is all. Simple install in about 30 min.
