Work out how much you can actually load into your caravan before you hit ATM. Start with tare and ATM off the compliance plate, then subtract water, gas and gear to see what's really left.

Estimate only. Your actual tare varies with factory options and dealer-fitted accessories — get your specific van weighed rather than relying on the brochure figure. See How Much Can Your Caravan Carry? Payload Explained and the Water Weight Calculator.
