Roadside weight checks: 40% of caravan rigs over ATM as vans outgrow the utes towing them

Caravan World has published sobering numbers from NSW Police mobile weighing operations in western Sydney: of 44 towed combinations inspected, nearly 40% exceeded their maximum Aggregate Trailer Mass (ATM), 36% exceeded the tow vehicle’s GVM, and 18% breached Gross Combination Mass limits outright. Perhaps most telling: 43% were operating at 90–99% of their rated GCM — technically legal, but with no safety margin left for the gear, water and passengers most tourers actually carry.

Not recklessness — arithmetic

The striking part of the reporting is the diagnosis. “In most instances, it’s not people being reckless,” Ford’s chief program engineer Justin Capicchiano told Caravan World. The problem is structural: Australian caravans have grown heavier — the CIAA’s own 2026 data shows vans over 6 metres dominating sales — while the dual-cab utes towing them were never engineered for today’s loaded weights.

The maths compounds quietly. A 3,500 kg-rated ute sounds adequate for a 3,300 kg van — until you add a canopy, drawers, a second battery, recovery gear, two adults, a full tank and 250 kg of ball weight. “You end up having to compromise on everything,” Capicchiano said. Every accessory on the ute eats the same GVM/GCM budget the caravan needs.

Our tow-vehicle matching guide walks exactly this trap — the gap between headline towing capacity and what’s actually legal once the vehicle is loaded.

What non-compliance costs

Roadside fines run from hundreds of dollars to over $1,000 depending on the state. The bigger exposure is insurance: an overloaded rig can be deemed unroadworthy, potentially voiding claims even when the other driver caused the accident. That’s the scenario that turns a fender-bender into a six-figure personal loss.

Detroit-style hardware is arriving

The industry response is telling: Ford’s 2026 Ranger Super Duty XLT was engineered specifically for this problem — an 8,000 kg GCM and 4,500 kg towing capacity without aftermarket GVM upgrades. It’s effectively an admission that the standard dual-cab formula has been outgrown by the vans it tows, as we’ve covered across the heavier end of our catalogue where 4,000 kg+ ATMs are increasingly normal.

What to do this week

1. Weigh your rig loaded — a public weighbridge visit costs under $20 and is the single highest-value hour in caravan ownership
2. Run the GCM subtraction — GCM minus loaded tow vehicle = your real trailer budget; our weights guide has the worked examples
3. Re-check after every accessory — the bullbar, winch and canopy you added since purchase all came out of the same budget

The 43% running at 90–99% of GCM aren’t outlaws — they’re ordinary owners who did the sums at purchase and never re-did them. Don’t be in that cohort when the scales come out.
