How to use it

Using three scale weights for towing

For the most useful towing comparison, record the truck and trailer with weight distribution engaged, the truck and trailer with weight distribution disengaged, and the truck by itself. TowAtlas uses those three measurements to estimate loaded trailer weight, tongue weight and how much front-axle load the hitch restores.

What to verify before you rely on the result

Compare the calculated weights with the exact ratings for your truck, receiver, hitch, axles, tires and trailer. Scale results help you understand the load; they do not by themselves certify that a combination is safe or compliant.
