Go off-road with the Pawn Stars when they're presented with a 1960's Mercedes Unimog. A German military vehicle built to go just about anywhere, will the guys cross rocky terrain for this rare truck or will they tell the seller to hit the trail? Then, a guy marches in with a sign that hung on the Berlin Wall. Will Corey and Rick make a deal or will the item divide them? And later, a collection of 1980's Garbage Pail Kids trading cards has Chumlee reliving his childhood. Can he convince Rick that these are worth picking up, or do they belong in the trash?
