Rebuilding A Front Cap After A Guardrail Took The Corner Off

The coach came in on a transport truck with the driver side front corner opened up and the owner convinced it was a cosmetic problem. That reading is completely reasonable from the outside. A guardrail end treatment at low speed does not look like a structural event, and the visible damage was confined to an area about the size of a car door. What made it something else was where the cracks started. There were two of them, one at the headlight bucket and one about eighteen inches inboard and lower, and they were reaching toward each other.

Cracks radiating from a single impact point are usually a repair. The laminate has failed at a location and you can grind back to sound material, lay in the correct glass schedule on both sides where access allows, fair the surface and refinish it. That repair holds because the surrounding laminate is still doing its job. Cracks originating from two separate points, especially when they start to cross, mean the panel has failed as a structure rather than at a spot. Tap testing tells you how far. We taped the boundary of the dull zone and photographed it with a tape measure in frame, and it ran nearly two feet past anything visible in the original claim photographs.

That is the whole reason the first estimate was wrong. It was written from submitted images by an adjuster who had a repair operation available and a photograph that supported it. Nobody was being unreasonable. The photograph genuinely did not contain the information that would have changed the answer, because the information was a change in acoustic response across a surface, which does not photograph at all. What photographs is tape on a panel, and that is why we tape it.

The windshield frame was the second surprise and it came out of the measurement rather than the teardown. Chassis front section measurement against factory datum showed the driver side had moved. Not dramatically, but enough that the urethane seal on the windshield had broken, and a broken urethane seal on a Class A windshield is a leak that will find its way into a wall over the following two seasons. The owner had not noticed because the coach had not been out in rain since the incident. This is the most common way a collision becomes a water damage claim eighteen months later, and the only defense against it is measuring instead of eyeballing.

Parts were the long pole, which they almost always are on a molded cap. The replacement took four weeks to arrive and that time was quoted on day twenty four rather than discovered on day forty. During the wait the frame section was repaired and reset and the graphics reproduction work was done, because the original decal kit for this floorplan has not been produced in years and the artwork had to be rebuilt from photographs of the passenger side and printed as new film. Doing that work during the parts window is the difference between a sixty one day repair and an eighty day one.

The forward camera mounted to a bracket on the cap, which meant the whole driver assistance question came along with the body repair. A camera reinstalled on a new cap is looking at the road from a position that is close to where it was and not identical to it, and close is not a specification. Static and dynamic calibration were both performed and both scan reports went into the file the owner took home. That line item was not on any version of the estimate until we put it there, which is true on most recreational vehicle claims we see and is one of the more expensive omissions an owner can accept without noticing.
