Search for a Peugeot Boxer Auto-Sleeper and you could be looking at several very different vehicles.

That is the first thing worth getting straight.

Auto-Sleeper is the converter/manufacturer and the Peugeot Boxer is the base vehicle underneath. Over the years Auto-Sleepers has used the Boxer for everything from fairly compact panel-van conversions to full coachbuilt motorhomes.

So a Boxer Auto-Sleeper could be something like a Symbol that still looks broadly like a panel van, a rear-lounge Warwick, a fixed-bed Kingham, or a coachbuilt Nuevo or Broadway with a completely different body behind the cab.

That also means there is no single checklist that says “all Peugeot Boxer Auto-Sleepers do this”. If I were looking at one used, I would treat it as two vehicles joined together: the Peugeot underneath and the Auto-Sleeper conversion on top.

Why are there so many Peugeot Boxer Auto-Sleepers?

Auto-Sleepers has had a long relationship with Peugeot and the Boxer became one of its main base vehicles.

You only have to look back at the 2019 Auto-Sleepers range to see how extensive it became. Peugeot-based models at the time included the Symbol, Symbol Plus, Warwick Duo, Fairford, Kemerton XL, Kingham and Warwick XL panel-van conversions, as well as Nuevo and Broadway coachbuilts.

Things have moved on since then. By 2026 many of those familiar names are being sold new on Fiat Ducato bases instead, so the phrase “Peugeot Boxer Auto-Sleeper” is now particularly useful when you are looking around the used market.

And there are plenty of them about.

Campervan or motorhome? It could be either

This is where the terminology gets confusing.

Panel-van conversions

Models such as the Symbol, Warwick and Kingham use the original van body. Auto-Sleepers cuts, lines and equips the Boxer, but from outside it is still recognisably a large panel van.

That generally means a narrower body and a shape that is easier to place on the road than a large coachbuilt. The downside is that every cupboard, bed and washroom has to fit inside the original van shell.

Coachbuilt Auto-Sleepers

The Nuevo and Broadway are different. Here the Peugeot supplies the cab and chassis while the habitation body is built behind it.

That gives the designer much more freedom with width and layout, but you are now buying a proper motorhome body as well as a van. Body seals, joints, damp and previous repairs therefore deserve just as much attention as the engine and gearbox.

If you are unsure about the terminology, I have a separate guide explaining the difference between a campervan and a motorhome.

A quick guide to some of the Boxer-based Auto-Sleepers

This is not every model Auto-Sleepers has ever built on a Peugeot, but these are some of the names you are likely to come across when searching used adverts.

Auto-Sleeper Symbol

The Symbol is one of the compact van-conversion layouts. The 2015–2025 generation was around 5.4m long and was offered on Boxer or Ducato bases.

I would look at this type of conversion if keeping the overall size down mattered more than having a large permanent bed or rear lounge.

Warwick Duo and Warwick XL

The Warwick is all about the rear lounge. The Duo is roughly 6m long, while the XL uses the extra-long van and gives you more room at the back.

If you like the idea of opening the rear doors beside the lounge and having two long settees that can become beds, the Warwick makes a lot of sense.

Kingham

The Kingham takes a different approach by fitting a permanent rear corner double bed into the extra-long van.

That means you are not rebuilding the lounge into a bed every night, but of course the bed is using space all day as well. Whether that trade works for you depends entirely on how you use the van.

Fairford

The Fairford is one of the longer four-berth van conversions and has been aimed more towards buyers who need extra travelling and sleeping accommodation rather than a simple two-person layout.

Nuevo

The Nuevo is a compact coachbuilt rather than a panel-van conversion. Older examples are particularly common on the Peugeot Boxer and have been around since the early 2000s.

This is an interesting middle ground if you want the extra width and facilities of a coachbuilt but do not want a huge motorhome.

Broadway

Broadway models are larger coachbuilts and have appeared in several layouts over the years, including end-lounge, end-bathroom and fixed-bed versions.

With a Broadway it is especially important to look at the exact model suffix and layout rather than assuming two vehicles with “Broadway” on the side are basically the same thing.

What I would check before buying a used Peugeot Boxer Auto-Sleeper

This is where I would slow down.

A shiny interior can be very persuasive, especially when somebody has spent an hour polishing the cooker and arranging the scatter cushions. Unfortunately that tells you very little about what is happening underneath the van or behind the wall covering.

1. Start with the history

I would want to see the service history, MOT history and invoices rather than rely on “it has always been looked after”.

The exact Peugeot engine fitted varies considerably with age, and so do maintenance requirements. I would not use a generic internet rule for cambelt/timing-belt intervals – identify the actual engine and check that the work due for that engine has been done on time.

Low mileage does not automatically mean low maintenance either. Motorhomes can spend long periods parked up, so age-related servicing matters just as much as miles covered.

2. Drive it properly

Do not make the test drive a ceremonial lap of the dealer’s car park.

Try the gearbox properly, including reverse. Check the clutch, steering, brakes and warning lights and listen for anything that changes as the vehicle warms up.

Older Boxers crop up in owner discussions with all sorts of age-related repairs – gearbox work, corroded cross-members, suspension parts and electrical faults among them. That does not mean every Boxer suffers from those problems. It means an older motorhome deserves the same mechanical inspection you would give any other ageing van.

If an airbag or engine warning light is on, I would want to know why it is on and see it rectified rather than accept “they all do that”.

3. Look at the tyres, not just the tread

A motorhome can have deep tread and still be sitting on old tyres because it covers relatively few miles each year.

Check the date codes, sidewalls and condition as well as the tread, and make sure the tyres fitted are appropriate for the vehicle and load.

4. Damp matters more than shiny upholstery

On a coachbuilt Auto-Sleeper, I would want evidence of habitation servicing and damp/body-integrity checks.

Use your eyes and nose as well. Look around rooflights, windows, lockers, washroom walls, floor edges and anywhere previous sealant repairs are visible. Musty smells, staining, rippled panels or a suspiciously fresh patch of wall covering deserve investigation.

A small moisture meter can be useful for comparing suspicious areas while viewing a vehicle. A pinless damp meter suitable for caravans and building materials is one current example. I would use something like this as an extra pair of eyes, not as a replacement for a proper habitation damp report.

A pinless damp meter can be useful for comparing suspicious areas during a viewing.

Panel-van conversions can leak too, of course, particularly around added windows, roof fittings and other holes cut into the original shell.

5. Test the habitation equipment – all of it

Turn things on.

Check the water pump, taps, fridge, heating, hot water, lights, mains hook-up, 12V system and control panel. If the van has an underslung LPG tank, ask when it was last inspected and serviced.

Many Auto-Sleepers use Sargent electrical equipment. Owner forums contain plenty of discussions about batteries, charging, control panels and Sargent units. Again, that does not make them inherently faulty; it simply means I would make sure the system actually behaves as it should before handing over the money.

Check that the starter battery charges, the leisure battery charges from the sources it is supposed to, and the fridge operates on the modes fitted to that particular van.

For the Boxer’s conventional 12V lead-acid starter battery, a proper tester can tell you more than simply reading the resting voltage. The TOPDON BT100 12V battery tester is designed for 12V 100–2000CCA lead-acid batteries and supports flooded, AGM, EFB and GEL types. I would not assume that makes it a meaningful capacity test for every deep-cycle leisure battery – check the leisure battery type and the test method recommended for it separately.

A proper battery tester tells you more than a simple voltage reading.

6. Make the beds and sit where you would actually sit

This sounds obvious, but it is surprisingly easy to buy a layout rather than a motorhome.

Make the bed. Sit on the toilet. Stand at the cooker. Pretend somebody else is trying to get past you. Open the wardrobe and fridge at the same time. Try getting in and out of the cab with the table up.

A layout that looks enormous in wide-angle dealer photographs can feel very different when two people and a wet coat are inside it.

This is particularly important with Auto-Sleepers because there are so many genuinely different layouts carrying familiar model names.

7. Check the payload

Do not just count cupboards – ask how much weight you can actually put in them.

The payload depends on the exact model, base vehicle and options fitted. Add passengers, water, gas, bikes, an awning, food and all the other stuff that somehow migrates into a motorhome and the figure can disappear surprisingly quickly.

The vehicle plate tells you the permitted limits, not what the motorhome actually weighs today. If payload is important – and on a motorhome it usually is – a public weighbridge can tell you the actual weight. Compare that with the plated maximum authorised mass and axle limits, ideally with the vehicle loaded roughly as you would travel.

What I would take to a viewing

I would not arrive carrying enough diagnostic equipment to frighten an MOT tester, but a few small things are useful:

• a torch;
• a pinless damp meter for comparing suspicious areas;
• a suitable 12V starter-battery tester if the vehicle has a conventional lead-acid starter battery;
• a tyre pressure gauge;
• a phone so you can check MOT history, dates and model information while you are standing beside the van.

A simple AA digital tyre pressure gauge currently reads up to 100psi, so it is a handy little thing to leave in the van afterwards as well.

The important bit is not the gadgets though. Give yourself enough time to actually look at the vehicle.

What about parts for an older Auto-Sleeper?

This deserves checking before you buy a very old example.

Auto-Sleepers still has a factory service centre at Willersey carrying out habitation servicing, repairs and parts/accessory work. It also points owners of older vehicles towards the Auto-Sleepers Owners Club technical department.

However, as of September 2026, Auto-Sleepers’ own parts-enquiry page says it cannot currently assist with enquiries for vehicles registered before 2010.

That does not make a pre-2010 Auto-Sleeper a bad buy – there are plenty still happily travelling around – but I would be more interested in the condition of unique trim, windows, body mouldings and conversion-specific fittings if replacements might be difficult to find.

Mechanical Peugeot Boxer service parts are a different matter from Auto-Sleeper-specific conversion parts, so do not confuse the two.

Peugeot or Fiat?

If you are looking at later used Auto-Sleepers, you will also see Fiat Ducato versions of some of the same models.

Historically one important reason was automatic transmission. Peugeot versions were commonly manuals while Fiat could offer the Comfort-Matic option on some generations. More recently Auto-Sleepers has moved much more of its range onto Fiat, including familiar names such as Symbol, Kingham and Warwick XL.

So if an advert says “Auto-Sleeper Kingham” or “Symbol”, check the base vehicle rather than assuming it must be a Peugeot.

Which Boxer Auto-Sleeper would I look at?

I would start with the layout rather than the badge.

If I wanted something relatively compact and van-like, I would look at the Symbol type of conversion.

If a big rear lounge mattered more, I would look towards the Warwick Duo or XL.

If I wanted a permanent bed in a panel van, the Kingham is the sort of layout I would investigate.

And if I wanted more width and a more conventional motorhome interior, I would move away from the panel vans and look at the Nuevo or Broadway coachbuilts.

Then I would buy on condition, history and layout, not because one badge is supposedly the model everybody has to have.

A well-cared-for older Auto-Sleeper that suits the way you travel makes far more sense than a newer one with the wrong layout and a pile of deferred maintenance.

One last thought

The nice thing about the Peugeot Boxer Auto-Sleeper combination is the amount of choice in the used market. The awkward thing is exactly the same – there is so much choice that the name alone tells you very little.

Find out exactly which Auto-Sleeper model and layout you are looking at, check the Boxer underneath properly, then give the habitation side the same attention.

Do that and you are buying the actual motorhome in front of you, not just the polished advert.
