Giant Lock Box
They did not post the size specs so I did not know if it would fit. For now, I ended up finding a giant lock box that works fine. It is plastic and could be cut, but the surf spot is very public. The JLU 2.0T has started proving frustrating so I have also started taking the Taco to surf instead of the Jeep.
Also for trademark reasons I had to change my user name to CoolToys
