A fellow on another forum group proudly posted his recent invention: attaching a pair of shop made
bars to a plastic cargo shell mounted on his small trailer. Maybe I am being a fussbudget but I have an uneasy feeling about the safety of this thing. Knowing that highway speed winds and collision forces have been known to rip entire racks off of metal vehicle roofs, I have a hard time believing that a rack attached to a plastic box this way is a viable hauling set up. Maybe somebody else is more familiar with the tensile strength of these clamshell suitcases and can reassure me that his “clever” invention is not going to land a kayak on somebody’s windshield, Maybe he has a 2 x 4 reinforcing the attachments inside the clamshell – he did not elaborate.
I confess I was similarly chagrinned when my brother built his own J-racks out of glued PVC pipe fittings and elbows attached to wooden slats and then held on his factory roof rack with u-bolts. Fortunately the car he was using that on died and he has a pickup truck now.
