Verify the out-the-door price
This listing is priced $6,835 below the typical Sierra 3500 HD AT4, which usually sells around MSRP. An advertised price this far under the norm often means a mandatory dealer add-on package (paint/fabric protection, accessories, etc.) or fees aren't reflected here — they're added at the dealership and can erase the discount. Confirm the full out-the-door price before you count on this as a deal.

- On the lot 12 days — longer than 13% of Sierra 3500 HD listings in WA.

Time on the lot and prior price cuts are real negotiating leverage — a dealer carrying a slow-moving unit is more likely to deal.
