The popularity of this two-berth’s layout is down to its practicality.

It’s the perfect accommodation for a couple that values social living space and a great washroom over the convenience of a fixed bed.

In its way, the layout is luxurious. You get a large lounge, a kitchen with plenty of worktop and cupboard space, and a rear washroom with a large shower.

The floorplan appears in most manufacturers’ ranges, so to find one that’s right for you comes down to the detail, and there’s plenty of it in Coachman’s Vision, its cheapest range.

We took the 450, the smallest in the eight-model line-up, on tour in south Devon, where it stood firm and provided a welcome refuge from squally, early spring rain and wind.

The Vision might be the entry into the Coachman portfolio of caravans, but there’s nothing shouting ‘budget status’ here.

The build quality is sound, and uses the company’s ABC (Advanced Bonded Construction) system, with full-height ABS front and rear panels, and aluminium sidewalls.

ABC is designed to minimise the risk of water ingress and the maker’s confidence in its build skills is backed up by a 10-year water-ingress warranty. The system means you get an awning rail on each side.

The red, grey and black graphics of this Coachman caravan are understated.

Adding ‘Plus’ to its name – and £500 to the price-tag – is the panoramic front window, a new option for 2017.

It also adds 11kg to the Mass in Running Order, so comes with a weight-plate upgrade from 1296kg to 1350kg – which also boosts the payload from 123kg to a useful 166kg.

The three-piece front window, sturdy grabhandles, alloy wheels and glazed one-piece entrance door, positioned behind the axle, are not to be sniffed at.

But you won’t find any external access to the storage space under the sofas.

The Vision 450 Plus is fairly compact in shape, but the overall look is one of understated elegance.
