About this app
GVWR is the ultimate towing companion that helps you tow safely with ease. This free tool simplifies the process of determining if your setup is safe by letting you input your truck and trailer ratings, actual cargo weight, and tongue weight. Our app calculates if your setup is within safe limits, so you can stay safe on the road. Save multiple setups, so you can easily switch between setups for different trailers or cargo. With GVWR, you'll always know if you're towing safely.
