Sub Model?
 

Any ideas how to identify the sub model? Im not sure if mine is a Scottsdale or Deluxe or blah blah blah. Inside is just basic. So ive always assumed its a Base but it has Scottsdale dash plate but i think the guy before me may of just had it put on after he redid the interior. Is there sure way to know?

Not a whole lot of difference between the bottom end truck and a Scottsdale. Here is what GM shows included with the Scottsdale trim.

I'm not sure how they were doing it in '81 but my dad ordered a '79 Suburban with the Silverado package. It was a stripped down truck otherwise, no air, no cruise, no radio, vinyl seats but did have carpet and headliner. I guess those were the days when you could actually order something the way you wanted it.

If the SPID is present and correct for the truck, it should tell you how it was ordered. Quite possible it was ordered at one level and had a few options added that were normally part of a higher level package. Also possible a PO added some stuff somewhere along the line.

Why don't you describe what you have or show pictures to help us help you? Scottsdale come with the upgraded vinyl seat and rubber floor cover.
