2021 Jayco Redhawk Windshield Replacement with ADAS Recalibration — Sacramento, California
A 2021 Jayco Redhawk 26M on a Ford E-450 chassis took a highway rock strike that spread into a 20-inch crack through the driver's sightline. The windshield was replaced in shop in Sacramento with an OEM panel and the forward-facing camera was statically recalibrated the same day. Total invoice: $1,340, of which $325 was calibration.

"Two other shops told me they'd replace the glass but couldn't calibrate the camera. Having both done in one visit with paperwork was the whole reason I went here."Verified customer — Sacramento, CA
Why calibration is not optional
When a windshield carries a forward-facing camera, moving that camera by even a couple of millimetres changes where the system believes the road is. Lane-keeping and automatic emergency braking read from that camera, so any shop that replaces the glass and skips recalibration has handed back a vehicle with safety systems aiming at the wrong place.
Ask for the calibration certificate in writing. On a claim it also matters — carriers routinely reimburse calibration as part of the glass loss when it is documented as a separate line item.
OEM versus aftermarket on camera builds
For non-camera chassis, quality aftermarket glass is a perfectly good choice and saves real money. On camera-equipped builds the calculus changes: small differences in optical distortion or bracket position can cause a calibration to fail repeatedly, and a second attempt costs more than the OEM premium did.
That is why this job specified OEM glass from the start rather than trying aftermarket first.
Frequently Asked Questions
Does an RV windshield replacement need ADAS calibration?
Only if the windshield carries a forward-facing camera — common on 2019-and-newer Sprinter, Transit and E-Series based Class B and C coaches. On this 2021 Redhawk it was required, and it added $325 to the job.
Can a crack in the driver's sightline be repaired instead?
No. Even a repairable-size chip leaves slight optical distortion, and in the driver's primary vision area that is a replacement regardless of size.
