2027 GMC Sierra 3500HD in Highland, Indiana

A fifth-wheel or gooseneck trailer puts part of its loaded weight on the truck. Allow for that pin weight, the hitch hardware, passengers, tools and any bed-mounted equipment when you check payload.

Single or dual rear wheels?

GMC lists up to 38,000 pounds of available towing for a properly equipped Sierra HD 3500. A maximum gooseneck figure is not a conventional bumper-hitch rating. Ask to compare the labels on single- and dual-rear-wheel trucks and measure your parking space.

Check the space a dually occupies

Measure the widest point of a dual-rear-wheel truck against your gate and shop entrance. Check whether the rear fenders clear posts when turning. If both versions fit the trailer’s requirements, the truck you can park and use every day may be the better choice.

Put the 3500HD in the context of your load

Write down the loaded trailer weight, loaded pin weight and the combined weight you expect to move. Verify the individual truck’s rear axle, payload, hitch and combined ratings. A higher trailer rating does not raise every other limit.

Ask Circle to compare the stickers on a single-rear-wheel and a dual-rear-wheel Sierra. Contact Circle Buick GMC in Highland or call 219-227-4410.
