Reference / Source register

Every published limit has a paper trail.

Original manufacturer tables, their conditions, and the exact editions reviewed. Your vehicle and equipment labels supply the limits that a family reference cannot establish.

What the review establishes

Selected manufacturer material was checked against its table headings, occupied cells, footnotes, and equipment conditions. PDF table pages were rendered for visual review; official web material retains its documented section. Each numeric fact keeps its source location, revision, scope, original value, and review date. Codex performed the transcription review for this release; independent human editorial sign-off has not been recorded.

“Verified” describes the selected material reviewed in an edition. It does not cover every page in that document. Conflicting figures stay out of the published configuration set until a documented resolution exists.

Original files and page images are retained only in the local research cache. Public pages provide selected facts, our explanations, and links to the manufacturer. SHA-256 identifies the exact reviewed file; it is not a vehicle certification.

Known source disagreements

Withheld from coverage

Ford F-150

The 2026 hybrid table prints a GCWR below its own trailer maximum. No replacement digit is assumed. Receiver tables also describe different installed receiver variants; an overall family WD figure is not used as an individual receiver label.

Chevrolet Silverado 1500

Some one-page chart cells disagree with their model-year full guide. The 2026 Double Cab 5.3L Max Trailering row, for example, shows 11,400 lb in the chart and 11,300 lb in the guide. Affected rows are withheld. The 2024 chart also contains overlapping hidden text, so extraction alone is insufficient.

See each edition's review notes below and the coverage gaps for the practical effect of these issues.
