See what your caravan weighs once it’s loaded with accessories, cargo, water and gas, how much payload you have left, and whether it suits the way you travel and what you tow with.
ATM is the maximum your van's allowed to weigh, fully loaded, on its own, set by the manufacturer. What actually eats into that number surprises people: full water tanks, gas bottles, everything stored in cupboards and lockers, and anything added since the van left the factory all count toward it, not just what you can see. Log what's packed inside once, and OSCA calculates your Projected ATM against that limit, updated every time you add or remove gear.
Log what’s packed in your van once, and your ATM updates automatically every time your setup changes.
What happens to my ATM if I add a BBQ and two 20L jerry cans of diesel?
Worked out in OSCA
Loaded 3,225 kg, plus 46 kg added, gives a Projected ATM of 3,271 kg against the 3,500 kg ATM. Payload remaining drops from 275 kg to 229 kg. Jerry cans are estimated at 18 kg each.

Most people know their van has a maximum. What catches them out is payload, what actually counts toward it, and how easy it is to underestimate once accessories, water and gear are all added in.
Full water tanks, gas bottles, everything stored in cupboards and lockers, plus any modifications or accessories added since the base model, all count toward it. It adds up faster than most people expect.
