RV Towing Calculator

This FREE interactive calculator helps you quickly check whether your tow vehicle and trailer combination is within safe weight limits. Enter your vehicle and trailer specs from the door plate, add your passengers, fuel, and cargo, and instantly see how close you are to your towing capacity, payload rating, and GCWR.

What it checks:

• Towing capacity vs. actual trailer weight
• Vehicle payload vs. passengers, fuel, and tongue weight
• Trailer GVWR vs. loaded trailer weight
• Gross Combined Weight Rating (GCWR) vs. total rig weight
