GVW (Gross Vehicle Weight), also called MAM (Maximum Authorised Mass), is the maximum your motorhome can legally weigh when fully loaded with passengers, water, gas, and belongings. Exceeding it is a road-traffic offence and invalidates your insurance.
If you passed your car test after 1 January 1997, a standard B licence covers motorhomes up to 3,500 kg GVW. For heavier vehicles you need a C1 licence (up to 7,500 kg). Drivers who passed before 1997 already hold C1 entitlement.
Payload is the difference between your motorhome's unladen weight (MIRO) and its GVW. You can find MIRO on the weight plate inside the driver's door and GVW on the V5C or from our database. Use our motorhome licence checker for an instant calculation.
Weights differ because of engine choice, chassis cab variant, factory options (solar panels, awnings, air conditioning), and the base vehicle specification (e.g. Fiat Ducato vs Al-Ko chassis). Always check the specific vehicle you're buying.
Yes. Payload determines how much you can carry after passengers are accounted for. A motorhome with only 200-300 kg payload may struggle once you add water, gas, clothes, and food. Aim for at least 400 kg for comfortable touring.
