The GMC Trailering App is a guide to towing for beginners and professionals. Towing information is broken down into key areas in the Learning Center that include: Trailering 101, Hitches & Equipment, Safety, and an interactive Towing Checklist for use each time you tow. There is also a towing calculator to help you find the GMC vehicle that meets your towing and passenger needs. So whether you tow a utility trailer, boat, or travel trailer for recreation, or a tow commercial products for your business, GMC wants to make sure you have the information to do safely and confidently.
