The low-profile Fusion is the result of a partnership between Italian brand McLouis and UK-based Auto-Sleepers. The aim was to produce a coachbuilt motorhome with Italian style and innovative features that is very much tailored for the UK market.

There are four models in the range (the McLouis Fusion 330 as tested here, the 360, the 379, and the 373, which we named one of the best motorhomes to buy), all based on Fiat engines. There are also a range of motorhome sizes to choose from, with lengths varying from 6.59m to 7.41m.

To put it to the test, I took a fresh off the production line McLouis Fusion 330 away for a few days to the beautiful South Lytchett Manor Caravan and Camping Park, near Poole in Dorset, a campsite which was named the best motorhome site in the UK in our 2025 Top 100 Sites Guide.

Exterior and cab

As we found when we last took the McLouis Fusion 373 out in November last year, the motorhome’s exterior styling and graphics really do help to signal your arrival.

A light grey at the sides and back is embellished by bold strokes of black and smart typography, all complementing the white cab.

The Fusion has a full GRP body, including the roof and rear panel, and the hab door is on the UK-friendly nearside, with a single key, remote locking and a flyscreen and blind.

That single key can also be used to secure the garage, leisure battery storage, water filler, gas locker doors and the toilet cassette (don’t forget to make sure you know how to empty a motorhome cassette toilet). Above the entrance door is an awning light, and inside it, a small bin.

It’s a short step up to the cab from the front seating area. And perhaps the most notable feature here is the large skydome window above the windscreen, which floods the front of the vehicle with light. The skydome can be opened and has an integrated blind and flyscreen, which can be clipped together.

The newly designed built-in cab blinds at the driver and front passenger windows and windscreen are pulled out and clipped closed in seconds, and appear to be more robust than similar systems I’ve seen on other vehicles. With an MTPLM of 3500kg, there will be no need to worry about what licence you need to drive the motorhome, either.

In the cab, the well-padded and comfortable seats come with covers and armrests, and swivel into the front dinette.

The fully digital dash has a built-in 9in touchscreen and DAB radio, with Bluetooth, a reversing camera, Apple CarPlay/Android Auto and steering wheel controls. The camera displays automatically when you select reverse. Add in touring gadgets such as the best dash cam for a motorhome and you’ll be well set for a comfortable experience on the road.

Touchscreen comes with multiple functions

There’s a ‘smart box’ on the dash, so you can connect your phone to play music and use sat-nav apps. This acts as a coolbox, so your phone shouldn’t overheat. There’s a 12V socket, too.

The Fusion is powered by a 2.2-litre Fiat Euro 6D 140bhp engine, with an 8-speed automatic gearbox, an electric handbrake and Hill Assist, and a 90-litre fuel tank. The dash has plenty of functionality without being too fussy, and the 9in screen doesn’t dominate the cab.

The cupholders are well placed, and the handbrake is electrically operated.

Driving the motorhome was a smooth experience. It packs a lot into its interior, but at 6.49m long, the Fusion is easy to handle, with no rattling from the accommodation area and a good line of sight.

Lounging and dining in the McLouis Fusion 330

The interior has sharp good looks throughout – we particularly like the Urban Grey furnishing fabrics, furniture and styling. The grey stripe flooring (which you see if you remove the carpets) is especially classy. In fact, we shortlisted the entire Fusion range at the Practical Motorhome Awards 2025 for the motorhome for innovation category, with the bright interior standing out to us.

The driver and passenger seats rotate to the glossy white table, which has a small handle underneath that allows you to move it around so you have a small, comfortable seating area for four.

The facing two seats also come with motorhome seatbelts for passengers. It’s compact, but we found it ample for the two of us; so much so that they hardly used the larger seating area at the rear of the ’van.

There’s plenty of light here, too, with several spotlights above both the front dinette and the rear living space, and a window next to the front table.

There’s a large touch on/off light on the ceiling, next to a rooflight with a blind and a flyscreen.

Lights can be operated via a control panel above the inside of the door or by switches on a side panel next to the kitchen work surface.

Moving towards the rear, you come to a U-shaped lounge with a small table – a good spot for stretching out.

It’s not as bright here as the front of the vehicle, but there’s lots of natural light, with windows on both sides of the lounge and at the rear.

The table is deceptive, because a button releases it to rise and it flips out to double in size. With a little juggling in terms of positioning, you end up with a sizeable table with plenty of room for four, maybe more.

The fact that you can change the Fusion’s living and sleeping space through useful design features such as the moveable, adaptable tables is definitely one of its best-selling points – if you are looking for options when you’re buying a motorhome, this ‘van has plenty of them.

Kitchen in the McLouis Fusion 330

While the kitchen is perfectly adequate, perhaps it’s here where buyers will have to compromise.

On the plus side, it has a sizeable 137-litre fridge with freezer compartment and bottle drawer, and it’s well lit with that transparent rooflight and touch-control light.

The kitchen has limited work surface, even if it does have a large fridge and an oven/grill

There’s also lots of storage, with large drawers under the hob and cupboards above, plus extra space underneath the oven.

And yes, to its credit, there is an oven and grill below the sink, but it only has a two-burner gas hob (with piezo ignition and a glass cover and splashback) and there’s very limited workspace, so you would probably have to use the dinette table.

If the kitchen is central to your whole motorhoming experience, this might not be the layout for you.

Washroom in the McLouis Fusion 330

The good looks continue in the Fusion’s washroom, which has been thoughtfully designed, with storage and a light above the electric-flush toilet.

The combined shower and toilet compartment can be separated off by a concertina door, which is Velcroed shut when not in use.

The tap and showerhead are a single unit (l) and the toilet (r)

Above the basin is a sizeable mirror, lit by two touch-control spotlights. More light comes through a rooflight.

The handbasin tap pulls out for use as a shower, with a fixing point above, and a small button on the tap changes the water flow to shower droplets. First, you’ll need to remove the protective wooden board on the floor.

Sleeping in the McLouis Fusion 330

If a flexible sleeping setup is a feature of the best 4 berth motorhome for you, the McLouis Fusion 330 could be worth a look.

With three sleeping areas, there are plenty of accommodation options. The main bed is the rear, electrically operated drop-down double, which lowers from the ceiling at the push of a button. You simply press and hold the button until the bed drops into the correct position.

We tried to leave bedding on the bed when we raised it back during the day, but this wasn’t possible – you’ll need to remove it first.

The bed is a good size, measuring 130 x 110 x 190cm, but we would have preferred a bit more headroom.

The second bed is a single at the front (measuring 190 x 81cm).

Again, a similar principle, it lowers at the touch of a button, and has safety nets (as does the double to make sure you don’t fall out). Beds are accessed by ladders that clip onto their sides.

Underneath the main bed, there’s a sizeable single bed (with more headroom should you prefer it), which can be made up by adding an extra wooden section and a cushion.

Storage in the 330

For a medium sized ’van, at 6.59m long, the Fusion 330 punches well above its weight when it comes to storage (and the model has a decent payload of 590kg).

For a start, there’s a garage that runs across the back of the vehicle and can easily be accessed from both sides. On one side, it has a light and on the other, a heating outlet, should you wish to warm the area.

When it comes to loading the motorhome‘s interior, there’s excellent storage throughout, with lockers that have strong catches above the front dinette and on both sides of the lounge at the rear (16).

There’s a useful large wardrobe between the rear lounge and the washroom, and a small cupboard above the TV mounting point, where there are also light switches and an aerial socket.

Equipment in the 330

The main control hub of the habitation area is on a digital panel located above the door. Here you can operate the ’van’s entire 12V system.

You can also view the voltage for the vehicle and leisure batteries, control the lights (including the awning light), switch the water pump on and off, and check the temperature.

There are separate light switches around the ’van – by the sink, above the dinette and near the TV point. There are also reading lights above the beds.

Next to the main control panel is the Truma control panel for hot water and heating, a system working on both electricity and gas. It’s super easy to switch on and control the room and water temperature from here.

The heater blows hot air through various vents around the interior.

Alternatives to consider

You could take a look at the Adria Matrix 670 SL 60 Year Edition, a motorhome with an airy lounge that comes with plenty of anniversary goodies.

Another option to look at is the Benimar Mileo 294, another four-berth which has a nicely lit lounge and a comfortable rear island bed, as well as space for all four of you to dine in comfort.
