Tying lumber to roof rack.
For plywood i put two 2 x 4 s on the roof rack and place the plywood on top of those to stiffen the plywood otherwise it flops up and down at highway speeds.
The second option is the side racks.
With anything you plan on tying down you ll need three preferably four solid points of contact stability.
