ATM
Let AllBrand Caravan Services determine your rig’s Aggregate Trailer Mass (ATM). ATM is the total mass of your van and any incidental payload you add to the rig (in below diagram, sum of A, B, and C), for example, food supplies, water supply, gas, and any luggage you may have packed. The ATM of your van is manufacturer-specificed, or, alternatively, you can refer to the table below as a reference.
