Ideas re. keeping critters off our tow vehicle when camping?

Get a jar of peanut butter and smear the peanut butter around the trunk of a close by tree. Put it up about 4 feet high and make a 4ing all around the tree. The racoons will. E so busy trying to lick off the peanut butter, clawing and pulling each other down from the tree, they will leave everything in your campsite alone, and you will have entertainment from the window of your camper. And this really works.
