Chevrolet Silverado incl. Silverado LD — K2XX (third-gen) (2014–2019)

NICB's VIN manuals show the 1500 in Work Truck/Fleet/Base, LT, LTZ and High Country lines with 4x2 and 4x4 drive in 2014 and the Silverado LD (Custom, Work Truck/Fleet/Base, LT) in 2019. NICB 2014 prints LTZ and High Country badges for the K2XX 2014-2018 trucks, but they are not aliases here because the T1XX carried them from 2019 and aliases are not year-scoped; the 2019 LD is Custom, Work Truck and LT only. GM's own lists in this doc's sources cover four years: the 2015 Silverado 1500 fleet order guide (one RPO page, which every row cites), the RPO list of the 2017 Silverado/GMC Sierra electrical body builder manual, and the 2018 Silverado 1500 and 2019 Silverado LD Double Cab fleet order guides (repository copies of GM's PDFs, cited by page for the sampled rows). That manual list is shared with the Sierra and with the heavy-duty and chassis-cab trucks, and no page in it is specific to the 1500, so it only adds 2017 to codes the 2015 guide already prints with the same meaning. No GM list for 2014 or 2016 is in the repository; a corroboration sample of 85 codes was checked against the 2018 and 2019 fleet order guides and GM Authority's 2016 and 2017 RPO-level change pages (see Other sources), and those years are added only to the sampled rows. The 2018 and 2019 years are cited to the guides' pages; 2016 and 2017 changes rest on GM Authority's articles. No source here separates trims, so every row is a 2015 code, some also seen in 2017 and, where sampled, in 2016, 2018 or 2019.
