Sierra 1500 Diesel Only

Diesel: Confirmed via VIN decode or dealer verification. When automated tools disagree with the dealer's own site, we trust the dealer.

Bed Length: GMC doesn't encode bed length in VINs. We verify this via explicit listing text. ✓ = Explicitly confirmed Standard/Long Box. ⚠ = Not known to be short, but not explicitly confirmed.

Sourcing: Nationwide scan sorted by value. Dealer prices are advertised; taxes/fees extra.
