The most important line of your V5C is not there.
You can turn it every which way, search between the boxes, compare it with your neighbor’s: the payload is written nowhere. It only exists if you do a subtraction, and nobody does that subtraction before buying. For us, it gives 494 kilos. It seems huge until you start counting.
So let’s count, with official figures, those from the registration document of our Hymer, and not forum estimates.
Reading the paperwork, field by field
The document is deliberately unreadable, or at least that is the impression it gives. Below is what the important fields say on our own French registration certificate, so you have a real example in front of you rather than a generic table. Read it as the source document for the 494 kg, then read the British translation underneath it: the two do not use the same labels, and that mismatch is where people get lost.
| Field | Value | What it means |
|---|---|---|
| B | 28/04/1999 | First registration. The vehicle is 27 years old, and will become a classic on April 28, 2029 |
| D.1 | FIAT | The chassis, a Ducato series 230 |
| F.2 | 3,400 kg | The GVW, the maximum loaded mass. Under 3.5 tons, so B license required |
| F.3 | 5,200 kg | The maximum mass of the whole, including the towed trailer |
| G.1 | 2,906 kg | The national unladen weight. That’s what we subtract |
| J.1 | VASP | The national type, specialized motor vehicle |
| J.3 | CARAVAN | The body type |
| P.3 | GO | Diesel |
| P.6 | 9 HP | The administrative power |
| S.1 | 5 | Seating places, so a maximum of five people, weight included |
Remember two things. F.2 minus G.1 equals your payload, and that is the only operation that matters. And S.1 does not say how many you can carry, it says how many seat belts you have: five seats in a vehicle with 494 kg of payload means five people weigh something, and there is nothing left for water.
The same operation on a British V5C
The F.2 and G.1 codes above come from the European harmonised registration document, and they exist word for word on a German or an Italian certificate. They do not exist on a V5C. Britain uses its own labels, so here is the translation, and the second column is the one to write on the back of your hand.
| What you are looking for | On a V5C it is called | The catch |
|---|---|---|
| Maximum loaded weight (F.2) | Revenue weight, in the weights block | It is the figure used for road tax, and on an up-plated vehicle it can disagree with the plate. Where the two differ, the manufacturer’s plate in the door frame or engine bay wins |
| Unladen weight (G.1) | Mass in service | Only reliably printed on newer registrations. On a nineties import it is often simply absent, and then you have no starting number at all |
| Payload | Nowhere | Same as everywhere else in Europe. Nobody prints it, you subtract it |
| Maximum authorised mass (MAM) | On the VIN plate | The plate is the legal reference and it also gives the two axle limits, which the V5C does not |
The practical consequence for a British buyer is unpleasant and worth knowing before you drive to a viewing: if the mass in service is blank on the V5C, the payload cannot be calculated on paper at all. You are then down to the brochure figure, which is optimistic by design, or to a weighbridge ticket, which is the only honest answer. On an older or imported van, ask for the weighbridge ticket. If the seller has never had one, that is itself the information.
494 kg: what remains once we’ve filled up
The number does all the work by itself; you just need to align what you are actually carrying. For us, the fresh water tank holds 120 liters, so 120 kilos, because one liter of water weighs one kilo and that’s the only place in the camper where the conversion is that brutal. Two full gas bottles, including the bottle, is around 50 kilos. Two adults, 140 kilos.
Add it up: 310 kilos. And we haven’t packed a single piece of clothing, a single computer, or a single pot yet. There are 184 kilos for a whole life left.
The empty weight trap
There is a misunderstanding that skews all calculations, and it lies in the very definition of unladen weight. Two concepts coexist and do not cover the same thing.
The national unladen weight (G.1)
This is the one on your French registration certificate. It corresponds to the vehicle as it left the factory, in its homologation configuration. It says nothing about added options, what the previous owner installed, or what you have installed yourself.
On an older vehicle that has been used, between a solar panel, a second battery, a bike rack, and an antenna, it’s easy to add several dozen kilos that are written nowhere.
The mass in working order
This is the European concept, and it already includes some things: the fuel tank filled to 90%, fluids, onboard tools, and a conventional driver weighing 75 kilos.
In other words, depending on the value you use, the driver is either already counted or not counted at all. This is exactly the kind of discrepancy that makes you think you’re comfortable when you’re not.
And on top of that, European regulations allow a 5% tolerance on the declared unladen weight. On a vehicle weighing three tons, 5% is 150 kilos. So, in our case, almost a third of the total payload can evaporate between the paper and reality.
What weight does to your licence
This is the most concrete consequence, and it is read off one figure. At 3,400 kg we stay under 3.5 tonnes, so a category B licence is enough. That is one reason manufacturers fight to stay under the threshold, even if it means advertising a ridiculous payload.
Go over it and you change worlds: C1, a medical, and a complete reassessment of who in the couple can legally drive. Which is also why up-plating a motorhome is not the miracle everyone imagines: the number on the paper changes, and so does the licence category that goes with it.
And here is the part of the British system that almost nobody writes about for motorhomes, even though it decides who can buy what. If you passed your test before 1 January 1997, C1 is already on your licence, granted automatically, up to 7,500 kg. Half the people reading this are entitled to drive a four-tonne motorhome and have no idea. It changes the whole shopping list, because it removes the 3,500 kg ceiling that pushes manufacturers into those absurd payloads in the first place.
The sting comes later. That inherited C1 is removed on your seventieth birthday unless you actively renew it, and renewing means a D4 medical to the stricter Group 2 standard, sent in with a D2 application, then repeated every three years. It cannot be done through the ordinary online renewal. So a couple who buy a 4.5-tonne A-class at sixty-five are buying a vehicle that one of them may not be allowed to drive at seventy-one, and the other may not be either. Book the D4 before the birthday, not after: the entitlement lapses on the day, and you do not get to drive on hope.
Where to get weighed, and why almost nobody does it
A weighbridge can be found everywhere, and this is the point I find most unfair about this subject: it’s neither expensive nor complicated, yet most camper owners have never done it. In Britain the ones that work are council recycling centres and waste transfer stations, agricultural merchants and grain stores, builders’ merchants and quarries, and the public weighbridges that some councils still run. Many will weigh you outside busy hours for a few pounds, and the rally weigh-ins run at some motorhome shows do it axle by axle for nothing.
The right method involves two passes. The first, the complete vehicle, loaded as you would actually travel, including tanks. The second, axle by axle if the setup allows, because the total may be fine while one axle is overloaded. A heavily loaded rear storage compartment, overhanging behind the wheels, puts the rear axle in overload while the overall balance remains within limits.
I’m not going to give you a weight ticket with a number on it; what I can give you here is what the official document says and what the calculation gives. What I can say, however, is what we have observed in hindsight: at the beginning of vanlife, we tended to overload, and looking back years later, I realize how we were overloaded at the start. Without ever knowing it at the time.

Overloading: what you really risk
There are three levels of consequence, and they are not equal at all.
In France, where we are registered, it is a fourth-class fine that steps up every 500 kg over, in the region of ninety euros a step. In Britain the penalty is graduated the same way but by percentage of overload, handled by DVSA at the roadside, and it can go to a court fine rather than a fixed penalty once the overload gets serious. In both systems, taken alone, the fine is not what should scare you. That is not where the real risk lives.
Here’s what really ruins a day. Beyond a certain threshold, the enforcement officer can prohibit the vehicle from moving until the overload is removed. In practice, you unload on the roadside, with your belongings spread out in front of everyone, and you leave when the weight is right. There’s no negotiation possible and no tourist exemption.
This is the argument that wakes people up, and it needs to be stated honestly. An overload does not make your contract disappear overnight. But in case of an accident, it gives the insurer a factual element to discuss your share of responsibility, because an overloaded vehicle brakes less well and handles worse. It’s a risk of litigation, and it’s more than enough to motivate a weighing.
What weight does to the vehicle
Even before the regulatory question, there is a mechanical question. The GVW is not an administrative figure chosen at random: it’s the mass for which the brakes, suspensions, running gear, and tires have been designed. Driving above that is not just a minor infraction; it’s using components outside of their intended purpose.
The most direct issue is the tire. A camper tire has a load index, and this index assumes a given pressure. Loading more without correcting the pressure means working the sidewall beyond its range, and on a vehicle that drives little and ages a lot, it’s the best way to turn an already old tire into a problem. The rest of what changes while driving, braking distance, acceleration, sensitivity to crosswinds, we detailed in our article on driving a camper van.

Read moreAnd when buying, what do we look at?
One simple operation, and it takes ten seconds: ask for a photo of the V5C and of the VIN plate before you even get in the car, then subtract mass in service from revenue weight, or plated weight minus weighbridge ticket if the V5C is silent. If the result is less than 400 kilos on a vehicle for two people traveling long-term, it’s an alarm signal, not a detail.
This number is all the more important because it is impossible to correct afterwards. You can repaint furniture, change a cassette, redo the electricity. You cannot create payload. It’s probably the only completely uncorrectable purchase criterion, and that’s why it’s included in our article on buying an old camper van even though it doesn’t appear in any ad photos.

Water in a van and motorhome: finding it, filling it, managing it
How your van water system works, where to fill up (including free), how many days you really last and the habits that save it, from years on the road.
Read moreThe corollary is quite amusing: on an old vehicle with a short payload, the first layout decision is not to add, but to choose what we will not take. Our 120-liter tank is not filled to the brim before each stage, and the way we manage water on board owes as much to weight as to the availability of filling points.
Weight and GVW: what we are still asked
Where do you read the weights on a British V5C?
Not under F.2 and G.1: those codes belong to the European harmonised certificate and do not exist on a V5C. Britain prints revenue weight for the maximum loaded weight and mass in service for the unladen weight, both in the weights block, and mass in service is often blank on older or imported vehicles. The legal reference in a dispute is the manufacturer’s plate in the door frame or engine bay, which also gives the two axle limits the V5C never shows. And the train weight, the vehicle plus a trailer, is the figure on that plate, not on the V5C.
Can you increase the GVW of a motorhome?
On some base vehicles, yes, through an uprating done by the converter or a specialist with a new plate and an amended V5C. Two limits appear quickly. The regulatory one: above 3,500 kg a category B licence is no longer enough, and you are into C1, which you either inherited from a pre-1997 test or have to sit and then keep alive with a medical after seventy. The technical one: changing the number on a plate changes nothing about the brakes, tyres or suspension. On an old base vehicle it is rarely a good idea.
Why does the actual weight of my motorhome never match the manufacturer's specifications?
Because the unladen weight is a theoretical value, calculated on a production vehicle, and European regulations allow a 5% margin on this value. On a vehicle weighing three tons, 5% represents 150 kg, or one third of a typical payload. Add the factory-installed options and everything that has been added since, and the only reliable figure becomes that of the weighbridge.
Should you drive with full or empty tanks?
Empty when you can, because water is the only heavy item you can choose not to carry. One hundred liters is one hundred kilos that are useless during the journey and return for free to the arrival tap. The nuance is that driving with a half-full tank makes the mass shift in turns and braking: empty or full, but avoid half-full on a long road.
What weight can a pavilion bed support?
The value is indicated by the manufacturer, often on a label near the bedding, and it generally hovers around 200 kg for a two-person cabin bed. The key point not to miss is that this load is part of your payload: it does not add to the GVW, it is part of it. Two people sleeping upstairs means two people who count in the calculation, even when stationary.
What weight can be put in a hold?
Here too, the manufacturer gives a maximum value, and it is much lower than one might think, often only a few dozen kilos. The reason is not the total weight of the vehicle, but the structure of the floor and the overhang: a rear cargo area is far from the axle, so every kilo there has a greater impact on the distribution. It is the part of the vehicle where we load the most and where we should load the least.
Does a rear bike rack count towards the payload?
Yes, twice. The bike rack itself weighs, the bikes do too, and the whole thing adds to your payload like any luggage. And since all of this is located behind the rear axle, overhanging, the effect on the distribution is amplified: it relieves the front, which lightens the steering, and it overloads the rear. With electric bikes, which easily weigh 25 kg each, you quickly run into a real problem.
Can overloading cause a problem with insurance?
This is the argument that wakes people up, and it deserves to be stated correctly. Overloading does not make your insurance disappear overnight. On the other hand, in the event of an accident, it gives the insurer a concrete element to discuss your share of responsibility, because an overloaded vehicle brakes less well and handles the road less effectively. It's a litigation risk, and it's more than enough to justify a weigh-in.
What do you actually risk at an overload check?
In Britain the roadside check is DVSA’s, the penalty steps up with the percentage of overload, and a serious one goes to court rather than to a fixed penalty. But the part that ruins the day is the same everywhere: the officer can issue a prohibition, and the vehicle does not move until the weight comes off. In practice you unload at the roadside, in front of everybody, and you leave when the figure is right. In France, where we are plated, the same event is a fourth-class fine stepping up every 500 kg, plus the same immobilisation.
How much does a weighbridge cost?
From nothing to a few pounds, depending where. Council recycling centres and waste transfer stations, agricultural merchants, builders’ merchants and quarries almost all have a weighbridge, and many will weigh you outside busy hours for very little. Some motorhome shows run a weigh-in axle by axle for free, which is the version worth queuing for. The right method is two passes: the whole vehicle loaded as you actually travel, then axle by axle if the layout allows, because distribution goes out of limits before the total does.
