Evidence status

Verified: exact VIN appears on archived photographed SPID, build sheet, and certification label. SPID YG8 Bonanza Package C and Z62 Sierra Grande; build sheet YG8 Promo Pkg. Royal Sierra 15 emblems are physical evidence. The code wording does not establish a production total or independently authenticate a named Royal Sierra factory edition. Later seller history, mileage, and the VIN-less July 2025 appearance remain qualified.

Factory documents

Archived photographs of the SPID, build sheet and certification label each repeat TCL146S511045. The SPID reads YG8 Bonanza Package C, Z62 Sierra Grande, 63E Saddle Knit trim, Yuba Gold/Frost White two-tone paint, E63 Fleetside and M40 Turbo Hydra-Matic. The build sheet identifies model TC10903, LS9 350 V8 and M38 three-speed automatic, and calls YG8 “Promo Pkg.” The M38/M40 wording is preserved as a document difference; neither document spells out “Royal Sierra” or establishes a production total.

Physical vehicle evidence

Photographed Royal Sierra 15 fender emblems support the truck’s later presentation. Their factory installation and the originality of present paint, trim and components are not established by the photographs.

Owner or seller statements

The ended eBay item 198593877527 displayed 77,554 miles and a $22,900 asking price; it does not establish a sale or lifetime mileage. A later seller called the original dealer “Morris & Sons GMC” and claimed long ownership, original paint and “1 of 500.” Those claims are not established by the recovered factory papers; the build sheet names King and Morris in Union City, Tennessee.

Later research

The May 26, 2025 Purvis/Proxibid auction, ended eBay listing and later dealer presentations are appearances of the same VIN. The July 14, 2025 Sullivan/BigIron truck is a probable visual match only because the recovered material lacks a VIN. The Proxibid page was indexed with this VIN but did not open in the September 26, 2026 check; archived source photographs were used for the factory-label analysis. Current custody and location are unknown.

Sources

Factory-document photographs from the Purvis Auctions / Proxibid lot archive: SPID, image 101-38; build sheet, image 101-32; dealer/order detail, image 101-35; and certification label, image 101-37. The SPID, build sheet and certification label each visibly carry TCL146S511045. These four source-hosted images were retrieved and visually rechecked September 30, 2026. The auction landing page could not be reopened in that check; the previously recorded May 26, 2025 event date was not independently reconfirmed from that page.

The SPID records YG8 Bonanza Package C and M40, while the build sheet uses YG8 Promo Pkg and M38. These are preserved document wordings. Neither document labels this VIN “Royal Sierra” or gives a production total. The build-sheet dealer detail reads King and Morris; the later seller’s Morris & Sons wording remains a separate, unresolved attribution. The certification label’s manufacture-date area is damaged and is not transcribed here.

eBay item 198593877527 publishes the exact VIN, a 77,554-mile reading and a US $22,900 asking price. The ended listing was retrieved September 30, 2026; its ended/no-longer-available notice does not establish a completed sale or realized price. Mileage, ownership, original-paint and production-number statements remain seller claims.

The Sullivan/BigIron July catalog, page 20 lists a Royal Sierra survivor. It is retained only as a possible appearance lead: the recovered material does not establish a VIN match to TCL146S511045. It is not an independent factory-package or sale-result source.

Source images remain hosted by their original publishers and are linked, not reproduced here. Current custody, lifetime mileage, component originality, production total and the July vehicle’s identity remain unverified.

Open questions

Does any factory paperwork explicitly assign the Royal Sierra name or original emblems to this VIN? Resolve the King and Morris versus Morris & Sons dealer wording, the July 2025 VIN-less appearance, lifetime mileage, ownership history, originality, sale result and current custody. No production total is documented.

Documented identity and factory equipment

The photographed Service Parts Identification (SPID) label, build sheet, and certification label each carry VIN TCL146S511045. The build sheet identifies model TC10903, an LS9 350 V8, and M38 three-speed automatic; the SPID says M40 Turbo Hydra-Matic. These are the documents’ different notations, not proof of a component change.

The SPID reads YG8 BONANZA PACKAGE C and Z62 SIERRA GRANDE, with 63E Saddle Knit trim, Yuba Gold/Frost White two-tone paint, and E63 Fleetside box. The build sheet calls YG8 “PROMO PKG.” Photographed Royal Sierra 15 fender emblems are physical evidence of this truck’s presentation. The recovered factory paperwork does not spell out “Royal Sierra” for its YG8 code or establish a production total.

One truck, several appearances

The ended eBay listing, item 198593877527, publishes this exact VIN and a 77,554-mile display. Its $22,900 figure was an asking price; the ended status does not establish a sale. The May 26, 2025 Purvis/Proxibid auction and later dealer or marketplace presentations refer to the same VIN. The Proxibid page was indexed with this VIN but did not open in the September 26, 2026 source check; its factory-document photographs are described from the preserved research archive. The July 14, 2025 Sullivan/BigIron appearance is only a probable visual match because the recovered auction material lacks a VIN.

The build sheet names King and Morris as the receiving dealer in Union City, Tennessee. A later seller calls the dealer “Morris & Sons GMC”; that relationship is unresolved. Longer ownership, original-paint, and “1 of 500” statements are seller claims. Displayed mileages across listings do not verify lifetime mileage or continuous ownership. Current custody and location are unknown.

Sources and limits

The linked factory-document photographs and listing citations are identified in the Sources section above. The September 30, 2026 review directly rechecked the four Proxibid document images and the eBay listing; the Proxibid landing page and the July lead’s VIN were not verified in that review. The photographed labels document their visible contents, not a complete chain of custody or the originality of every surviving component. No third-party photographs, scans or private customer details are reproduced here.
