No. Silverado 3500 HD pickups are sold with single or dual rear wheels. Cab, engine, rear-wheel arrangement and equipment determine each truck’s capability. The truck’s own ratings cover its towing and payload limits, including the weight of passengers, bed cargo and the trailer’s load on the pickup.
No. The gas 3500 HD has a properly equipped gooseneck or fifth-wheel towing limit of up to 19,080 pounds. The 36,000-pound gooseneck figure belongs to a different, properly equipped truck. Conventional, fifth-wheel and gooseneck ratings are separate limits.
No. Silverado 3500 HD pickup trims are WT, LT, LTZ and High Country. LT and LTZ offer the Trail Boss package. ZR2 belongs to the separate Silverado 2500HD lineup and is not one of the four 3500 HD pickup trims.
Payload is the weight the Silverado 3500 HD can carry, including occupants, cargo and the load a trailer places on the truck. Cab and equipment choices affect that limit. Towing capacity describes a different load, so a truck must stay within both its towing and payload ratings.
LT and higher trims have the 13.4-inch touchscreen with a 12.3-inch driver cluster. WT uses a seven-inch screen. Those cabin choices are offered within the Silverado 3500 HD pickup lineup alongside gas or Duramax power and single or dual rear wheels.
No. Silverado 3500 HD chassis cabs and complete pickups have separate body, payload and combined-weight specifications. A pickup’s own ratings apply when it is sold as a complete pickup. Lucas Chevrolet handles the pickup’s cab, engine, rear-wheel and hitch choices together.
The 3500 HD pickup’s fifth-wheel rating, hitch equipment, payload and combined-weight rating all apply to the loaded trailer. Occupants, bed cargo and the trailer’s weight on the truck use its payload. Lucas Chevrolet can match the pickup’s engine and equipment to that trailer.
