Is a Sierra 1500 sold differently from a Silverado?

No. Both use the same journey. They are closely related trucks, but the model, trim and equipment are recorded for what your truck is, and dealers bid on that.

Can I sell a Sierra AT4 with off-road modifications?

Yes. Record each change from factory specification with photos, and say whether the original parts come with the truck. Dealers decide what those changes mean for their bid.

Which Sierra you have

The Sierra 1500 comes as a Regular Cab, Double Cab or Crew Cab with more than one bed length, in two- or four-wheel drive, in trims including Pro, SLE, Elevation, SLT, AT4 and Denali. Engines have included turbocharged four-cylinder, V8 and diesel options. Features such as the multi-function tailgate are worth recording because they are part of the specification.

Showing a premium truck accurately

Higher trims carry equipment that is easy to leave out of a description: power running boards, a head-up display, upgraded audio, adaptive cruise control. List what is fitted and check that it works. Photograph the bed, tailgate, hitch, wheels and the leather or cloth seats.

Records worth finding first

Service records, the title or loan payoff details, every key, and receipts for significant work. You can check the VIN for open recalls on the NHTSA website before you list, so the dealer reading your record sees the recall status alongside everything else.
