Ram Cummins locking fuel cap
finally found a locking fuel cap for the Ram Cummins. http://bem-auto.com/blog/dust-on-the-ezloc/

I'm not so worried about a cap that locks so I've still got the plastic factory plug stuck in mine. When it wears out I'll figure out another cap but at two years it still works fine. I'm on dirt roads a lot so I'm not really a fan of the capless setup.
