For the side table on my TD I made my own brackets
To start with I fastened a piece of 3/4" aluminum angle to the bottom of the table.
And for the bracket on the side of the trailer I used a piece of laminate flooring that I cut, shaped and painted to make what looks like a decorative body-side molding when the table is not attached.
I fastened the new molding to the side of the trailer with scews and put 2-3 washer's between the molding and the body to leave a nice snug space for the aluminum angle on the bottom of the table to slide into.
