Epic boat anchor! I LOLed. But the question begs to be asked. Who owns a Tacoma and has need for a boat anchor of this sorts? Not to mention the chain is almost too perfectly wrapped around the shaft, the shadows on the links are wrong, and you have decided not to tie down such an item at all.
To quote Joe from Family Guy when watching Peter crash the Petercopter in his front yard: "How do you afford all this stuff?!?!"
