The premier self-service towing weight calculator providing the only 13 point safety report.
Caution: This is not a pre-purchase calculator. Use RV Tow Check.
The appropriate worksheet for completing this report is found at Step 1.
If all your safety margins are displayed in GREEN, that's great! You have carefully paid attention to your vehicles’ load. Pat yourself on the back. Although this report is a good indicator of a safe load, Fifth Wheel St.'s 5th Wheel/Gooseneck Truck and Trailer Weight Safety Report can never substitute for the advanced weighing procedure consisting of wheel by wheel weighing. Whenever possible, weigh each wheel position at a location that provides the advanced towing safety report. Visit the Wheel-by-Wheel Weighing Resources page to find a location near you.
If any of your safety margins are displayed in RED, then you are towing with a potential driving hazard. It's your responsibility to consider what you think is safe for your towing situation, whether it's 4 pounds overweight or 4000 pounds overweight. You need to take a careful look at how your vehicles are loaded. You may need to remove or relocate some items to better balance the load. In some instances, you may need to purchase a tow vehicle with higher towing capacity or purchase a trailer with less gross vehicle weight rating (GVWR).
