Y'all forgot the red light bulbs in the cab lights, to make it look like a cow taxi... Also, you have to keep all the stickers on your windshield from the past 5 years worth of rodeos, so you dont get hassled if you feel like going to any rodeos which you choose not to participate. . Beer cans add points, but you must have a fully stocked cooler, or "Coffin" as I call it, full of only the finest cheap beers, like Keystone, or Milwaukee's Best Light. . Another point to make sure of is to have a complete flavor selection of Boone's Farm readily available with the cheap beer selection. As far as inside the truck, no need to get some expensive seat covers, just use some cheap mexican blankets. they work awesome! When your seat cushion goes south, take it out and rebuild it with baling wire, and foam from an eggcrate mattress cover!
BTW, the Cowbell has to be hung with a dog choke chain, to prevent theft. . I found out the hard way, but now I take my ding dong everywhere, and dont have to worry anymore!
Hope these ideas are beneficial to some of y'all!
