RPO Codes: One oddball in my list

This question may be posted somewhere around, but I didn't see it in my searches:
A few days ago I was watching a video linked from here regarding the G80 RPO Code indicating the Eaton Locking Rear Differential. I got curious and started looking up all my RPO Codes for fun. I've got a 2007 Silverado 1500. All my RPO codes seemed right / fine with the exception of "1LT". I have no idea what this one is, and I've only seen it noted on Malibu codes as the LT-I trim package. I've checked the sticker, it's not a wrong note on my end that I can see. I still have the original window sticker, and it's an LT-II Package on there.

Anyone have any ideas on the "1LT" RPO Code? If not, it's no big deal, I was just wanting a complete list for fun.

I'm using these two sites for my lookups:

Thanks all!

Just go to http://www.compnine.com/vid.php and do the free 24 hour demo. You put your vin in and they list all the RPO codes and explanations. I did it and then copy and pasted them into a word document and saved it so I will always have it. It will list everything from alternator to tire size
That stinks. I used it last month and got the free demo. It used to be completely free.
