Our used camper came with this HOWEVER, given the flimsiness of the particle board on the base cabinet, the attachment spot is pushing right through. We'll have to decide whether to brace or to remove, but would recommend a brace be included inside the cabinet for this.
Thanks for the comment. When I installed the shelf, I built a T-shaped support out of 1x4s and attached it to the inside of the cabinet to attach the hinge and brace to. Very solid. — LuckyDuck
