Chevrolet Tahoe — T1XX (2021–2027)

GM's own lists for this generation are the GM Upfitter electrical body-builder lists for 2022, 2023 (filed by GM Upfitter for 2023 and 2024, dated 2023 here) and 2026, which are the same files as the Suburban's and cover the Tahoe and the Suburban together, and the Tahoe fleet order guides for 2025, 2026 and 2027: the retail and fleet guide and the police package and special service guide of each year. The retail and fleet guides give trim availability for the Comm, LS, LT, RST, Z71, Premier and High Country columns (the guides label the FL column Comm; Notes here call it FL), and the police guides for the Police Package (9C1) and Special Service (5W4) columns; "retail guides: S on all trims" means all seven retail columns, "police guides: S on both columns" the two police columns, and a plain "on all trims" a code printed by both guide families; Notes carry O for optional and S for standard or included in the trim's equipment group, for the latest year the guides print the code. NICB's 2021, 2025 and 2026 VIN manuals show the FL, LS, LT, RST, Z71, Premier and High Country Tahoe, and a PPV (Police Pursuit Vehicle) in 2025 and 2026. The Suburban has its own doc and guides; every code the Suburban guides print is also printed by the Tahoe guides of the same year, and 9C1, 5W4 and Z56 and the other police and special service codes are printed by the Tahoe police guides only. About two dozen body-builder-list codes that the Suburban doc leaves to this one because only the Tahoe police guides print them (5T5, 5Y1, AMF, AU7, J55, K6K, RAV, UD7 and others) are printed by the Tahoe police guides and are kept here with those pages cited. No list in the archive covers 2021 or 2024, so a year missing from the Years column means no source was read for it.

The RPO Codes dialogs captured with each fleet order guide (the …-fleet-order-guide-rpo-codes.txt files) and the Print All guides' own RPO CODES pages list the same codes; the Print All guides were cited because they also give trim availability and the COLOR AND TRIM pages.
