For those considering a new tow tug two key questions need to be answered.
1. What is the Aggregate Trailer Mass (ATM) of the loaded caravan to be towed? The official numbers will be on the caravan compliance plate.
2. Will the tow vehicle builder warranty that in the case of their vehicle the ATM does not exceed its rated towing capacity?
The application of ATM sorts out the pretenders when it comes to towing claims.
ATM (Aggregate Trailer Mass): Is the mass of the laden caravan when not connected to the tow vehiclewhen carrying the maximum load recommended by the manufacturer. The actual total laden mass of the trailer must remain below the ATM.
It must not exceed the rated towing capacity of the tow vehicle.
A Weight Distribution Hitch (WDH) cannot change ball weight. It is a towing aid which helps braking and steering by distributing the load forces more equally The major benefit is that better road contact is achieved by the front wheels of the tow vehicle and this provides better control of the rig
