Lock your Tailgate!
Lock your tailgate! Arizona ranks 3rd in the country for tailgate theft. Tailgates are ridiculously easy to steal and ridiculously expensive to replace (thus helping explain why they are stolen with such frequency). For under $50 (in most cases) you can get a lock that is easy to install and will thwart most would be criminals. While you are at it, pick up a bike cable and padlock for that spare tire hanging under the bed, also low hanging fruit for those unsavory types.
