An ATM (Aggregate Trailer Mass) upgrade increases the legal maximum weight of your caravan or trailer when fully loaded and unhitched — water, gas, gear, and fit-out included. Many caravans are overloaded before they even leave the driveway once full of touring gear and water tanks.
A properly engineered ATM upgrade reinforces the trailer's chassis and suspension to safely carry the extra load, backed by an engineer's compliance certificate for registration.
Without certification, an overloaded trailer is not road-legal, may be uninsured in the event of a claim, and can fail a roadworthy inspection. Read our full guide on GVM vs ATM →
