904 of 2,080 live listings carry the Z6A Hitch platform to accept Gooseneck or 5th wheel hitch, read from the window sticker or OEM code. Updated hourly.
Our catalog lists the 2026 Silverado 3500HD at 20,000 lb conventional on all four trims, Work Truck, LT, LTZ and High Country, each with the Duramax diesel and a 3.42 axle. The gooseneck and 5th-wheel numbers come from two RPO codes: Z6A, the hitch platform for a gooseneck or 5th-wheel hitch, rated 30,900 lb, and NHT, the Max Trailering Package listed for the Work Truck, rated 36,000 lb. The listings above count which live trucks carry each code, read from window stickers and OEM codes, not dealer descriptions.
Counted only when the package shows on the truck's window sticker or in its OEM option codes, not in dealer text.

One catalog configuration per trim. Each trim comes in several engine, axle, cab and bed combinations with different ratings; a truck's own window sticker has its exact ones. A dash means the figure isn’t in our catalog or isn’t confirmed against an OEM source.
Verified packages with an OEM order code and what they change for towing. A rating is shown only where every verified source for that code agrees.
