I've always liked the looks of the PSD stinger rack. It would also protect the tailgate in a collision. But, wouldn't this be a pain to lift, drop, lift, step around, trip over? Of course, when down it would provide a good place to sit during lunch breaks on the trail. Can you design one with a simple (light weight) rear bumper, and gas can holder? Just curious.
I don't think anyone took their spare off for White Knuckle during the 2006 EJS. The JK (or your 37s) may be different, though.
