Delta is Lunar’s long-established, twin-axle flagship range. Priced at £24,395, it’s pitched against the top-end offerings from all the major manufacturers. Until recently it has looked dated compared to new styling from Swift Group, Coachman and Bailey. But a radical re-design for 2013 has changed all that, and the Delta TI took top honours in <i>Practical Caravan</i>’s March 2013 Triple Test against Bailey’s new Unicorn Cartegena and Swift’s Conqueror 645.

Here we take a look at the other half of the two-model range: the Delta RS with a side fixed bed and end washroom. This type of layout has dominated the twin-axle market for a few years. The RS’s floorplan is 6.34m long, but Lunar’s renowned lightweight construction technique keeps the MTPLM down to an impressive 1735kg.

Pitching and setting up

Lunar’s new front shape is striking and well crafted and the wide front door’s high-lift cantilever hinge action makes access a doddle. It’s surprising that Lunar has opted not to offer, even as an option, a trendy front sunroof. We agree that some may prefer roof lockers, but other brands can offer customers a seductive extra reason to trade in their old vans.

The Delta’s Al-Ko chassis comes equipped with ATC stability control, AKS stabiliser, shock-absorbers, two Secure wheel locks and Stabilform corner steadies. As you’ll see in the equipment list, exterior specification continues at a high level and the Delta trumps its fellow Clubman’s spec with an underslung 40-litre water tank and an Al-Ko jack (to help fit two wheel locks).

The heart of the electric system is in a seat front, convenient for set-up. The dual-fuel Alde radiator heating system takes longer to warm up than blown air heating but its renowned comfort comes from its even, draught-free heat. If your Delta is already on a pitch, you can even start the heating early using your mobile phone.

In our <a href="/reviews/caravan/28155-lunar-clubman-si">Lunar Clubman SI review</a> we voice concern (albeit unverified by testing) about shortish lounge radiators. This van has the same radiators but longer seats, so again we fear for cold spots in sub-zero outside temperatures.

Lounge

It’s hard to find anything not to like in the Delta’s front lounge. The seating is luxurious and full of nice details and the seats, both 1.84m, are plenty long enough to relax with your feet up or to seat six if you’re throwing a party. Six could even dine together if the extending chest top is combined with the free-standing table. The new upright front shape allows welcome room for head and shoulders in the front corners and the wide front shelf is useful.

Pleated blinds are smarter and easier to operate than the sprung roller type, so it’s a shame that some makes just use them on side windows. So congratulations to Lunar for fitting pleated ones all round. In our opinion the best night-time look is with the curtains left in their ties, especially with the under-locker LED strips enhancing the mood.

The comprehensive lighting is all with power-saving LEDs. In addition to the under-locker strips, there’s a ceiling light and four corner spots and two large flush corner fittings flood the lounge with ambient light. The TV can go on the front chest or the mid-van cupboard, thanks to generous provision of aerial, satellite and power connections.

Kitchen

You expect an impressive kitchen in a twin-axle van and the Delta RS does not disappoint. An 180-litre two-door fridge freezer is sited opposite, leaving room for three base units housing an array of drawers, shelves and slide-out baskets, as well as the dining table. The oven and grill are full width and a useful electric hotplate supplements three gas burners.

Above, two solid and three translucent doors give access to three separate cupboards for crockery and taller, light items. Light comes from a ceiling fitting and LED strips under and inside the lockers. Being spoilt by the Clubman SI’s excellent microwave oven position gives rise to our only gripe – with all the space in the Delta, it would be good to see it sited low down instead of above the fridge.

Washroom

This is a well-equipped, spacious washroom with the latest ceramic bowl Dometic toilet, a good-sized, lined shower cubicle and heating from a domestic-type radiator. Perhaps the washbasin could be a little bigger and we would have liked more work surface for toiletries. Taps and fittings are smart and modern. An opening window and rooflight ensure plenty of natural light and ventilation, and lighting upholds the standard set by the rest of the van.

Beds

The double bed’s deep, pocket-sprung mattress should ensure a comfortable night’s sleep and, at 1.9m x 1.35m, it’s as big as a domestic double, apart from the cut-away required for the gangway. There are conveniently placed reading lights and shelves and general illumination, from a ceiling light and another flush corner fitting, is better than most. There’s even a third TV point with a multi-position bracket opposite the foot of bed and two extra CD/radio speakers.

The front seating makes two single beds measuring 1.84m x 0.73m or it will convert to a double bed supported on pull-out slats. Even with the drawer chest in place it’s a generous 2.11m x 1.44m.

Storage

For bulky items, there’s a huge, uninterrupted space under the double bed. The bed base lifts high for inside access, but stowing large items from outside would need a bigger door. There’s plenty of space under the front seats, with convenient, full-length front flaps.

The battery of four drawers in the wardrobe base is impressive. And there’s lots of room for small items throughout the van, thanks to mid-shelves in all the roof lockers.

Verdict

For the Delta RS, Lunar has used a proven and popular floorplan, executed it well and endowed it with an impressive kit list. The twin-axle van’s extra length is noticed in the long front seats, the big fridge/freezer and lengthy kitchen unit. At 6.34m internally, it’s one of the longest vans on the market but still only weighs 1735kg fully laden, making it suitable for a wider range of towing vehicles. So, with its striking new styling, it’s going to claim a place on most buyers’ shortlists.

Conclusion

Pros

  • Good sized beds for four, comprehensive kit list and an MTPLM of just 1735kg

Cons

  • Needs bigger luggage door, there are potential cold spots in the lounge and no front sunroof option
