Yea I mounted mine to the boxed area inside of the rail on angle 2x2 . Just added 2 risers and swivels . Just need more space to store rods without taking them down.
We have 18 rods with the 4 riggers , copper, lead core, wire and braid dipsies. The sides aren't big enough to store that many , Don't want to remove the cushions up front, because my wife and daughter like to layout. Working on a layout on the back just to the sides. to stand them up on the trip out and back.
If it works out I will post a pic. May just have to take down a few and put them in the rod boxes.
