Decoding RPO Codes

[Big Smoky]

While changing the windshield wiper bushings, I was excited to see the RPO codes on a plate, on the passenger's side, under cowl. I've searched here and google searched to try to decode the RPO codes with no luck. Does anyone have a list of all the RPO codes for our trucks and what they mean?

I guess I'll sign up here to see what the hell an RPO code even is. :hehe:
