# Rear cap impact with hidden frame displacement on a 40 foot diesel pusher

Backed into a steel bollard at a storage yard. Visible damage was a cracked rear cap and a bent ladder. Teardown found the rear frame extension displaced 11 millimeters out of square and the generator bay floor buckled, neither of which was visible with the cap on. The carrier's initial estimate was written from the cap outward and missed all of it.

## Vehicle

40 foot Class A diesel pusher, Freightliner XC raised rail chassis

## Operations performed

- Priced collision teardown, rear cap and bumper fascia removed to expose the frame extension
- Three dimensional measurement against factory datum points, documented before any pull
- Sequenced pull on the frame rack, re measured between each stage
- Generator bay floor section cut out and a new panel scarfed in, welded by certified personnel
- OEM rear cap ordered through the builder channel, seven week lead time disclosed at authorization
- Cap bonded, faired, primed, and refinished with a mapped blend into both rear side panels
- Supplement filed with the measurement report attached, approved without a reinspection delay

## Outcome

The coach came back square, the generator slide out tray tracks correctly again, and the carrier paid the supplement because the measurement report made the hidden displacement a document rather than an argument. The owner kept a coach the carrier had initially proposed to total at 63 percent of value.

## Numbers

- Price band: $4,500 to $25,000 plus
- Calendar time: 3 to 8 weeks
