| Evidence to collect | 258 | 268 |
|---|---|---|
| Model identity | Full suffix; distinguish the 258U reference | Full chassis code and model year |
| Dimension authority | Exact 258 variant sheet | Matching body-builder table |
| Working fit | Deck height, mounts and axle weights | Body condition, overhang and axle weights |
Low-profile and high-power labels have consequences
The verified 2020 Canadian 258U sheet describes a specific high-power configuration. It is not a numerical authority for a 268 or for every 258LP listing. Have the seller provide the labels and build record, then use the correct manual column before comparing dimensions or replacement-body plans.
Make condition and installation costs comparable
List body repairs, liftgate service, tires and immediate chassis work separately for each candidate. Compare route history and engine hours, including stationary equipment use. Resolve modifications and campaign status before negotiating around an asking-price difference that may simply reflect deferred work.
