New passenger van. Took the seats out because the dealer said the noises were from the seats. Not so. Rattles like a hammer knocking around but appears to come from the tailgate area. Jack and tools are wrapped up in towels and secure. Not the cause. Will be going back and forth to the dealer until they acknowledge it and fix it. Dealer says, "This is a cargo van and they make noise." No one pays $44k for a cargo van. This is a passenger van and shouldn't rattle!
