This is probably a dumb question,but what is an rpo code ? Is it the options your truck has in it ? If it is how/where would you find them...

RPO is Regular Production Order. It is the options included in the vehicle from the manufacturer.

Look inside the glove box, you will find more than you wanted to know....

You can also go to the Dealer/Stealer and ask them to print out the description of the RPO if you give them the VIN.

Hmm... My truck is a 2002 and was originally purchased in October of 2002, which I assume was one of the last of the '02's. It has some codes from the '03-up, and others I can't find anywhere. Odd. And, son of a bitch, it did have floormats! I bet the damn dealer stole 'em

Which RPO's you still need?
