The weight of the car and trailer must be reduced by 10% for every further 3280 ft (1,000 m) (or part thereof).

Gross Vehicle Weight Rating (GVWR) - 10750 lb

This is the maximum amount of weight GMC Sierra 3500HD is rated to carry (engine, chassis, fluids, passengers, cargo, load - everything). It is often determined by the manufacturer and is indicated in the owner's manual or on the inside of the drive's door panel.

Curb Weight - 6231 lb

Axle Ratio - 3.73

It is the same for all trims.

Drive Type - rear-wheel

All-wheel or rear-wheel drive vehicles are best suited for towing, while front-wheel drive vehicles can haul much less weight.

Transmission - 6-spd auto w/OD

Do not overload your vehicle while towing, as this can cause the transmission to overheat and fail. If your transmission has "Towing mode" - be sure to turn it on.

Turbocharger - intercooled turbo

It is the same for all trims.

Turbocharged engines produce more power, so if you need a vehicle for towing, choose the one equipped with a turbo.

Wheelbase - 141.6

The longer your vehicle's wheelbase, the less likely the trailer you tow will push down on the rear axle and lift the front end.
