    Chevrolet Silverado HD — K2XX (HD) (2015–2019)

    The Chevrolet Silverado HD is the heavy-duty 2500HD and 3500HD pickup: NICB's VIN manuals list its 2500 and 3500 series in Work Truck/Fleet/Base, LT, LTZ and High Country trims with 4x2 and 4x4 drive for 2015 (under Silverado) and for 2019 (under Silverado HD). GM's 2016 Silverado 2500HD and 3500HD fleet order guides (Wayback captures) give the trim groups 1WT Work Truck and 1LT LT, the 6.0L V8 (L96), the gaseous 6.0L V8 (LC8) and the Duramax 6.6L diesel (LML), and every row with the year 2016 cites them; the 2019 2500HD and 3500HD captures hold only dimension and trailering pages, which name the L96 and the Duramax L5P. GM's own 2017, 2018 and 2019 Silverado 2500HD and 3500HD order guides, read as GM Authority's PDF copies, add those years to the codes they print; no source covers 2015, so no row claims it, and the guides' special-equipment (SEO) and ship-thru codes are not listed. In Notes, "only in" names the model whose guides alone print the code.
