If you would like to provide feedback on the GVWR + Payload calculator, please contact us below. We’re always open to ideas, changes, revisions, weight rating specs, and much more. If you find a curb weight, GVWR spec, or Max payload spec on your specific make and model that is incorrect, please let us know. We have done over a year of research on vehicles years, makes, and models to get the most accurate data available, however, we may have missed a spec or two. Please let us know if you see a need for any change within the calculator.
