Evidence standard
Methodology
History reports tell you what happened. Valuation tools tell you what similar trucks list for. We focus on what the configuration may cost next, with uncertainty shown explicitly.
Publication states
Research means a target exists but no public verdict is allowed. Reviewed means evidence is being adjudicated. Published means the record passed automated and human publication gates.
Evidence hierarchy
- Official/OEM/regulatory primary sources.
- Observed market transactions or clearly identified current listings.
- Specialist repair/service evidence with disclosed context.
- Owner/forum evidence used for hypothesis generation, never as sole proof of a hard number.
No fake precision
Ranges, sample sizes, dates, and uncertainty are shown whenever available. A missing number is preferable to a fabricated one.
Corrections
Corrections update the visible record and remain auditable in repository history. A strong claim can be downgraded when better evidence arrives.
