Wondering if there is a site where one can plug in the vin # and get the list of what the truck was built with. Until you guys told me what the cooler lines were I didn't know the truck had both an engine and trans cooler, I just found out it has a cold package as I just unwrapped the engine block heater cord etc. Would love to know other things like which differential it has or whether it has a locker etc. THanks Larry
Any way to find option list?

i went to my local dealer and the service manager ran one free... it's a "build list" and shows every thing that was included on the truck when it left the factory.. VERY helpful, when you buy a used truck..
Look at the inside of the glovebox door. There should be a bunch of 3 digit codes printed on a label (known as RPO codes). You can look up the meanings for them on many different websites, but alot of them are incomplete and some of them are actually WRONG.

is the best and mostcomplete list of RPO's that I've found to date. BTW- You will not be able to find ALL of your codes. There are 8 of them for my '87 Chevy that aren't listed anywhere. I believe these codes were used primarily for factory purposes and have no relevant meaning.
