Frequently asked questions
Caravan payload is the difference between the caravan's MTPLM (Maximum Technically Permissible Laden Mass) and its MIRO (Mass In Running Order). It's the total weight you can add: water, gas, clothes, food, bikes, awnings, and any dealer-fitted extras like motor movers.
Find your caravan's MTPLM and MIRO on the weight plate (usually inside the front locker or on the A-frame). Subtract MIRO from MTPLM to get your total payload allowance. Then add up everything you plan to carry and check it fits within that figure.
Yes. A typical motor mover weighs 30-40 kg. If it was fitted after the caravan left the factory, it comes directly off your available payload. The same applies to leisure batteries (20-30 kg), satellite dishes, and upgraded awnings.
In most cases, yes. MTPLM minus MIRO gives you the published payload. However, some manufacturers state a specific payload figure that may differ slightly due to standard equipment variations. Always check the weight plate on your specific caravan.
A family of four should look for at least 150-200 kg of payload. This allows for water (20-40 kg), food and clothes (40-60 kg), bikes and outdoor gear (30-50 kg), bedding, and miscellaneous items. Lightweight caravans may struggle to provide enough payload for larger families.
Towing an overloaded caravan is illegal. You risk fines, penalty points, and invalidated insurance. More importantly, an overloaded caravan handles poorly, causes excessive tyre wear, and is more likely to snake at motorway speeds.
A weighbridge is the only way to know your true loaded weight. Published MIRO figures are factory averages and may not include dealer-fitted extras. Many touring clubs recommend weighing before your first trip and periodically after.
