So you are saying that if I get the right adaptors, that I could broadcast a mobile dvd players sound into the truck's stereo systems speakers? If they are going through the stereo system, then the it would broadcast to cordless headsets, and therefore, the wife I could have peace and quiet?

Yup.. you got it. Just go to radio shack and tell them you need a headphone plug to headphone plug wire.. unless your DVD has RCA outs, then you need RCA to headphone... simple!
