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... (more), 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?
