On our 2nd TT the previous owner used moulding to make the supporting side rails. He simply glued the moulding to the sides of the ward and drove a couple of nails in at the ends of the moulding where it met the ward. We never had a problem with those shelves loosening up, but we also only kept that TT for 3 years.
