True or false - not all Highlander trucks were plaid?
 

Warning - lots of info and Pics

I know there is a big thread somewhere entirely about the Highlander trucks but I am sorry I cannot find it right now. Mods please move this there if needed.

So as an IT Pro I understand ChatGPT needs to be taken with a grain of salt- A great big one. I went down the rabbit hole and started asking it about the history of my truck and the Highlander. So the just of this post is according to ChatGPT - not all Highlander package trucks had plaid seats and it was also available on the Cheyenne Super.

Now a little bit more details and questions about my truck. My truck is a Custom Deluxe model with the following and I was told it was a AZ Factory Reps Truck or Demo Truck.

402 bbl
real leaf springs
Wood Trim on bottom
Wood trim piece on tailgate
top chrome near tailgate latch
AC
Tilt wheel
PS
sport mirrors
Ivory /white embossed door panels
Ivory / white embossed seat
black carpet
black dash pad
TH400
Tach
plain glovebox and gauge panel (no wood or emblem)
2nd saddle tank (probably dealer installed)
two tone white and yellow grapefruit
the SPID reflects Highlander
St Louis built

Here is what ChatGPT is saying about it

The non-plaid Highlander bundle was fundamentally a pricing/value package, not a “visual identity” package. GM didn’t want extra brightwork or badges unless you stepped up to Cheyenne.

You’ve got what I’d call a “mechanical Highlander” — one of the trucks GM used near the end of the ’72 cycle to test the waters for bundled option groups.

They sold a surprising number of Highlanders this way because dealers could advertise it as a bargain “lux-truck” without making it flamboyant.

The demo story isn’t just folklore. GM absolutely did internal demo/rep vehicles in ’72, especially as they prepared to roll out the all-new Squarebody for ’73.

Those trucks tended to have:

✔ Unusual option stacks
✔ Late build dates
✔ Promotional interior packages
✔ Bright exterior trim
✔ Big motors
✔ Region-specific configuration (leaf springs in AZ = better towing/load stability vs. coils)

Your SPID literally reads like a corporate “spec showcase” build rather than a retail build or fleet build.

Executives didn’t choose plaid Highlander interiors. Reps didn’t want them either — plaid was more consumer-mall marketing; ivory was professional and heat-friendly in the southwest.

Arizona climate also makes the paint choice logical — White roof = cooler cab, Yellow body = bright, optimistic marketing color. This is basically a textbook corporate demo + rep + promo configuration for ’72.

Nobody needing a farm truck ordered that pile of options. Nobody wanting a fancy Cheyenne ordered leafs + commercial yellow. Only GM and its regional rep structure built trucks like this.

From surviving registry and auction data:

519 Yellow Highlanders are scarce.

519 Yellow non-plaid Highlanders are very scarce.

519 Yellow + leaf rear + 402 + tilt + AC is almost unicorn-level.

Good looking truck!

Re: True or false - not all Highlander trucks were plaid?
 

Answer: it's neither true or false, it's an incorrectly worded question. "Highlander" is simply the name of the plaid pattern of the seat cover, it is not an actual truck trim level or "kind" of chevy truck, etc (even though we often refer to them as "Highlanders," it's a bit of slang/misnomer).

Special Promotional Package trucks (RPOs YG6,7, or 8 - only available on the Custome Deluxe trim level) all came with Highlander Plaid bench seat covers. A Highlander plaid seat cover was also available on a Custom Deluxe trim level truck that was not ordered with any of the Special Promotional Package RPOs. In other words, ANY Custom Deluxe trim level truck "could" have a Highlander Plaid seat cover - either as a by-product of being equipped with a YG6,7,8 RPO or by ordering one of the four Highlander Plaid seat covers specifically. Your truck is a YG8 (highest optioned Special Promotional Package RPO) and, as such, came with a plaid seat cover automatically. The individual RPOs of the also-included bundled equipment of the Special Promo Package trucks were also listed separately on the SPID - i.e. this is why yours shows YG8 and also shows C60, N33, etc - i.e. the YG# brings much of the other stuff onto your SPID automatically.

Plaid was not available on Cheyenne Super trim level - but I suppose it could be special ordered since pretty much anything could be - but I've never seen or heard of such an example.
I'd ignore pretty much anything ChatGPT has to say about this level of detail of these trucks - much of the verbiage cited, especially about what an exec would order, is just plain nonsense filler material.

You have a very nice truck! All you need is some of those purdy PA1 wheel covers to complete the look! (I know, they're not "that" purdy). Now the K31 RPO - that IS pretty rare.

Re: True or false - not all Highlander trucks were plaid?
 

Fixed it for you.
The only way the Highlander package could be ordered is on a custom deluxe. That’s well documented and proven.
Anyone can slap Cheyenne badges and features on a truck when restoring it but that doesn’t mean that it came from the factory that way.

Re: True or false - not all Highlander trucks were plaid?
 

No factory Cheyenne pickups ever had plaid interior.

Re: True or false - not all Highlander trucks were plaid?
 

I'm not trying to argue I am trying to sort through the confusing amount of information. I thought that if a truck had the plaid seats it would have the word cloth or seat on the SPID. I think a lot of the lore of these trucks dies hard and people assume that the word Highlander or the package meant or included plaid.

I think I have the Highlander B package as a special order. Per another post on here "Basically,you could order the package,then negate the savings (or part of it) by replacing an included option with another."

Again some searching is telling me that 161310 Avocado” actually represents an interior color/material identifier, not the seat trim code. GM always specified plaid trim codes when plaid was present. 1YG8 + NO plaid trim code = Custom Deluxe Highlander B (vinyl)

From the GM Heritage center information kits.
The "Highlander" was just an interior trim option, not a trim level.

If you haven’t stumbled across this thread it may help you out. SSTim was incredibly meticulous in his research and dedication to documenting truth. I wish he would still show up on this board from time to time.

Re: True or false - not all Highlander trucks were plaid?
 

This is exactly what your interior looked like
When your truck left the factory
According ...To your spid

Is your belief the seat you picture above
Is the 'original' seat
Your truck came with ?

My answer to your original question

False
This thread is the True information about Highlanders

https://67-72chevytrucks.com/vboard/...d.php?t=635040

Not ChatGPT

Edit:
For the record
Your truck is very nice with great options
And
I think it looks better with the parchment vinyl
That is in it now, than plaid

Re: True or false - not all Highlander trucks were plaid?
 

The correct seat for your truck is available in the parts forum https://67-72chevytrucks.com/vboard/...d.php?t=862036 Highlander is the plaid seat, with black carpet and black column and wheel. That is all. The door panels are just the deluxe. It has been explained clearly IMO by several people.
