I cant tell what trim my truck is!

[Christopher Guy]

I have scoured the RPO codes and vin decoders and can not seem to figure out what my trim package is.

 

I assume its an LS but there is no 1234LS RPO code.

 

Here is a pic of the RPO codes:

It's an LS trim based on the VIN and this simple decoder.

RPO code 1SB on your tag = LS trim.  

 

Start on PDF page 134, the entire order guide for 2005 Silverado 1500 with all the option descriptions:

Under each trim level column under the name of the trims is the RPO code that identifies each trim level.
