Camping box, full conversion or roof tent? Three options, honestly compared

If you want to travel in your own vehicle, sooner or later you reach the same fork in the road: a removable camping box in the cargo area, a fixed conversion of the interior or a roof tent on the roof. All three lead to nights outdoors, and none of the three is the right one for everyone.

This article compares them along the same axes: purchase, effort until the first trip, everyday usability of the vehicle, weather and season, space and storage, removability and resale, and the legal classification. At the end there’s no recommendation for one option, but a match-up: which option suits which type of traveller.

Three options, three basic decisions

The camping box is a self-contained module that is placed in the cargo area and secured there. Sleeping, storage and – depending on the version – a pull-out kitchen are all in one unit. Nothing on the vehicle is permanently changed. It’s designed for vans and high-roof MPVs, such as a VW T6, a Ford Tourneo or a VW Caddy. How this works in detail is described in the article From van to camper – no conversion.

The full conversion permanently transforms the interior: panelling, insulation, screwed-in furniture, often power, water and heating. This turns the vehicle into a motorhome. At the far end of this scale is the bought motorhome – the full conversion is the self-built or workshop-built version of the same idea. If you’re wondering whether it should be a camping box or a motorhome straight away, you’re essentially comparing these two ends.

The roof tent sits on a roof rack and leaves the interior completely untouched. You sleep above the vehicle and live next to it. Inside, the car stays a car.

Purchase and the effort until the first trip

Reliable price ranges don’t belong in a comparison article because they quickly go out of date. The order of magnitude, however, is stable: a simple roof tent is usually the cheapest way in, provided a suitable roof rack is already there or can be retrofitted cheaply. A camping box sits above that. The full conversion has by far the widest range – from a frugal DIY build with lots of your own work to a workshop solution that reaches the value of a used vehicle. You’ll find concrete figures and cost blocks in the article What a camper conversion really costs.

More interesting than the price is the time until the first night. A camping box is delivered, inserted and secured – then you can drive off. A roof tent first needs a roof rack and two people to lift it onto the roof; after that, setting up at the pitch takes only minutes. A full conversion is a project: planning, materials, tools and, depending on the scope, weeks to months of work, or a workshop appointment with a corresponding wait. How much work actually goes into a DIY build is broken down in the article Building your own camping box.

What the vehicle can still do in everyday life

This is where the options differ most clearly. With a roof tent, the cargo area stays completely free. The vehicle remains an everyday car, can carry furniture, take the kids to school and still be a place to sleep at the weekend. You pay for this with vehicle height and fuel consumption: multi-storey car parks, car washes and low entrances become an issue, and the roof load sets a hard limit that’s stated in the vehicle documents and should be checked there.

With a full conversion, the question is settled: the cargo area is permanently living space. That’s not a weakness but the purpose – just irreversible, as long as the conversion is in.

The camping box sits in between. As long as the module is in the vehicle, the cargo area is occupied. Once it’s taken out, the van is a van again. That does assume, however, that you can actually get the module out and have somewhere to put it – garage, basement, carport.

Weather, season and sleeping comfort

A full conversion is the only one of the three solutions that can be permanently insulated and heated. Parking heater, insulated walls, fixed wiring: if you travel in winter or in cold high-altitude areas, there’s hardly any way around this type of build. For long trips in one go, the difference in comfort is also big, because nothing has to be set up and packed away.

With a roof tent, you sleep in a tent structure. The mattresses are usually good, the view is unbeatably beautiful, and ground moisture isn’t an issue. But wind, cold and persistent rain are still tent conditions. On top of that, you have to pack up every time you change location, and if you need to get out at night, you climb down a ladder.

The camping box sleeps in the closed vehicle. That protects against wind and wet better than a tent and less well than an insulated conversion. For the three seasons from spring to autumn, that’s enough for most people; for winter camping it’s a trade-off that depends on the vehicle and the equipment.

Space and storage

The full conversion wins this axis without discussion. Cupboards, kitchen unit, water tank, fridge, fixed seating area – everything can be planned so that every centimetre is used, and everything stays in its place.

With a roof tent, the place to sleep is up top, but the storage space is nowhere: gear, kitchen and clothing have to be organised in the vehicle or in crates. For travellers who travel light anyway, that’s no problem. For two people with kitchen equipment, a cool box and gear, the boot fills up quickly.

The camping box combines both in one unit: sleeping surface on top, storage in pull-outs below, a pull-out kitchen depending on the version. The limit is the size of the vehicle – you can’t get more volume than the cargo area offers. The quickest way to see which version offers how much storage is the model comparison.

Removal, resale and legal classification

A fixed conversion is married to the vehicle. When you sell, you sell both together, and the pool of buyers gets smaller: anyone looking for a van for their business doesn’t want a conversion. That can pay off if the conversion is well done – but it can also push the value down.

Roof tents and camping boxes are similarly well placed on this point: both can be removed, taken into the next vehicle or sold on separately. With a roof tent, transferability depends on the roof rack; with a camping box, on the interior dimensions of the new vehicle. For anyone who leases their vehicle, uses it for work or wants to change it in the foreseeable future, that’s an argument with weight.

On the legal side, the general picture is this: the three options sit differently in the regulatory landscape, and the details differ between Austria, Germany and Switzerland. Depending on its scope, a permanently installed conversion may require an inspection or a change to the vehicle documents – especially if seats, gas systems or the vehicle class are affected. A roof tent touches on the permissible roof load and the vehicle height. For all interior solutions, load securing and payload are the points that get checked if in doubt. This is a general classification, not a guarantee: what applies to your specific vehicle can only be clarified bindingly with the responsible testing centre or registration authority.

Which option suits which type of traveller

Criterion	Camping box	Full conversion	Roof tent
Purchase	medium order of magnitude, predictable	widest range, from DIY to workshop	usually the cheapest way in
Effort until the first trip	insert, secure, drive off	weeks to months or a workshop appointment	fit the roof rack, put the tent on with two people
Vehicle in everyday life	cargo area occupied, module removable	cargo area permanently living space	interior stays completely free
Weather and season	closed vehicle, three seasons	can be insulated and heated, suitable for winter	tent conditions, highly weather-dependent
Space and storage	storage integrated into the unit	most volume, freely plannable	sleeping up top, storage has to go elsewhere
Removal and resale	removable, transferable to the next vehicle	tied to the vehicle	removable, rack has to fit

The roof tent suits you if …

• you drive a car, estate or SUV without a large cargo area
• you mostly travel in the summer half of the year and in warmer regions
• the boot should stay free for gear – climbing kit, surfboards, bikes
• you often stay several nights in one place instead of moving on every day

The full conversion suits you if …

• you travel for several weeks or months at a time
• you also travel in winter and want heating, power and water permanently installed
• the vehicle is only there for travelling anyway
• you enjoy building or are willing to hire a workshop

The camping box suits you if …

• your van or high-roof MPV – such as a VW T5 to T7, a Mercedes V-Class or a VW Caddy – is also your everyday or company vehicle
• your trips range from long weekends to tours lasting several weeks
• you lease the vehicle, use it for work or want to change it in a few years
• you want to sleep in the closed vehicle and have storage and a cooking area on board

The match-up isn’t a ranking. If you drive to the coast for two weeks in August and surf during the day, a roof tent serves you well and cheaply. If you want to spend half a year travelling through Scandinavia, you’ll be unhappy with a box in winter. And if you need the van again for materials on Monday, you’ll regret a fixed conversion.

The next step

The decision rarely depends on the concept, but on the details of your own vehicle: interior dimensions, seat configuration, payload, planned trip length. If you’ve landed on the modular route, whether and how it works for your vehicle is quicker to clear up in a conversation than via data sheets. CampBoks® is on the road in 1,000+ campers; which configuration suits your vehicle is a separate calculation every time.
