Five steps to check your tow
Free, no account, about two minutes — checked against the manufacturer ratings.
Open the full towing calculator, or jump straight to the GVM calculator, caravan weight calculator or tow ball weight calculator. Looking up one vehicle? Browse towing capacity by make and model or check your vehicle's towing limits. Buying a van? See caravan finance and the caravan loan calculator.
Already weighed?
Use your real numbers, wheel by wheel
Enter per-wheel readings from portable scales, hitched and unhitched, and see the car, the towing and the caravan each checked against its limits, with every wheel's load and the balance drawn from above. Only have a weighbridge ticket? That works too.

The guesswork goes, not the options
Your customers enter their vehicle once, then see your whole range with their own towing limits beside it. The enquiry arrives with the context your team needs to help them choose.

Smart insights for this setup

- Ask about suspension, tyre pressures and a brake controller set up for your ride: small tweaks make a big difference to towing stability.
Illustrative result: customers see this against your own stock before they enquire.
