The long-lived Pageant was a hugely important range for Bailey Caravans, the mid-market model developing a devoted following before its replacement by the Pegasus in 2009.

The first van to feature Bailey’s trendsetting Alu-Tech construction system has evolved over the ensuing seven years through Pegasus II and the anniversary-special Pegasus GT65 into this, the fourth-generation Pegasus launched for the 2016 season.

Two models were dropped and three new layouts added – the fixed-nearside-bed Modena, the transverse-island-bed Brindisi and the twin-axle Palermo – but one of the most intriguing vans in the range is the revised Ancona.

Like the Palermo, it features a front lounge, an end washroom and a child-friendly rear bedroom, and the floorplan has been revised to right some of the shortcomings of the old GT65 Ancona.

In recent years, the middle-ranking Pegasus has struggled to establish itself against the wider, highly specified and not much costlier Unicorn, but this five-berth layout gives the Pegasus a unique selling point compared with the two- and four-berth-only flagship range.

With the Pegasus IV following hot on the heels of the revamped Unicorn, it’s no surprise to find that it follows the lead of the range-topper.

There are the same Polar White sidewalls replacing the GT65’s dated magnolia, the same rounded rear roofline and, of course, the new Bailey family look, featuring ‘flying B’ graphics in blue.

Alu-Tech kicked off the caravan construction wars and remains a logical way to build a modern tourer, with an extruded aluminium frame and sandwich panels bonded to it – the lack of external fixings reducing the risk of water ingress.

It’s better looking than before, but this construction tends to give a flat-looking front and rear, softened only by ABS bumper mouldings.

The full-height front window, introduced for the Pegasus GT65 in 2013, continues.

Inside, the main change has been in the rear bedroom, where the fixed bunks have been moved forward, making space for a wardrobe in the full-width end washroom.

Subtle revisions throughout give a sense of more internal space, despite the relatively narrow 2.23m body width. Headroom is an impressive 6ft 5in and is further aided by the adoption of perimeter LED downlighters in place of the ceiling rose.
