Big Holiday!

Sunliner’s spacious Holiday G510 has plenty of room to move…

Sometimes it's a bit hard to get a handle on everything available in the Sunliner motorhome range. The bottom line is, however, there’s something available for everyone – from the budget PRV campervan to a luxury Monte Carlo.

Fitting in amongst all this is the Holiday range, which whilst not being the most expensive, is certainly well up the ranks. Our review motorhome, the Holiday G510, is one of the largest and most expensive Sunliners available. It came with two slide-outs – one on either side – and was fitted out to Sunliner's spec three level, the highest available.

The Vehicle

Sunliner builds its motorhomes on a range of cab-chassis, but our test Holiday was built on an Iveco Daily 50C17. It came with a 3.0-litre turbo-diesel delivering 130 kW of power and 400 Nm of torque, driving through a 6-speed Agile gearbox – Iveco speak for an automated manual transmission (AMT). A driver’s air bag is standard on the Daily, but Sunliner has taken the option of a passenger air bag too.

In some ways the Iveco Daily is a bit like its Italian stablemate, the Fiat Ducato, which isn’t surprising given they come out of the same factory. The major differences being that whilst the Ducato is front wheel drive, the Daily is rear wheel drive and the Daily is available with heavier load capacities. In both cases they have a fair chunk of the motorhome market in Europe, which makes them fairly motorhome friendly from both a manufacturer’s and user’s point of view. 

In converting the motorhome Sunliner added a fully welded sub-chassis, called Torquo™ in Sunliner speak, to the main Iveco chassis rails. This was done according to Sunliner to improve both the vehicle handling and general weight distribution. 

For the body, Sunliner use one piece walls and a roof that uses a bonded Duplo foam core structure designed to give both insulation and strength, whilst keeping the weight in check. Those familiar with Sunliner motorhomes will immediately recognise the characteristic fibreglass mouldings at the rear, as well as the driver’s cab side steps. 

Like many a motorhome manufacturer, Sunliner use Seitz hopper windows to full advantage, whilst staying with the convenience of the well used Camec triple lock security door. External body fittings consist of the electrically powered awning and external wall light above the door, whilst the roof features a few items like a wind-up TV antenna and an Air Command Ibis air conditioner.  

Apart from the Thetford toilet cassette cubicle, battery bin and the gas cylinder bin under the offside slide-out, there are four other bins of various sizes. Only the forward nearside one is probably large enough to store a generator (but not run – it’s not vented), but given the high lip getting it in and out would be a bit awkward on the back. 

On The Road

Given the Holiday G510’s tare weight of 4040 kg it might have been possible to squeeze it onto a 4490 kg chassis, but Sunliner has wisely decided to use a 5200 kg chassis. That does mean an LR truck licence is required, but I reckon that's a small price to pay for the worry free load capacity. On the road the 3.0-litre 125 kW turbo-diesel pushed the Holiday along well enough and in many ways it’s no different from its contemporaries. The AMT gearbox is reasonably smooth on most changes, but has the usual sometimes-slow kick downs and hesitations at lower speeds. 

Like its contemporaries it’s a light commercial vehicle, but it’s more car-like than truck-like to drive as long as the usual precautions are taken for a slightly wider and longer vehicle. A reversing camera is standard on this model, as-is the Iveco radio/CD player, but something a little more upmarket would be nice, given this is a luxurious and upmarket motorhome. For extra passenger carrying the forward-facing dinette seat is fitted with two belts and is relatively handy to the cab for easy conversations. 

Living Inside

What two slide-outs do is a add a considerable amount of interior space – no surprises there. Even with the slide-outs closed the front kitchen/dinette area of the Holiday can be used without too much trouble, but down the back access to the full-width rear bathroom is denied by the east-west bed. Of course with both slide-outs open there's just about enough room for a small dance floor. 

On the subject of slide-outs, the rear control switch is oddly located. All the other essential controls are either above the entry door or on a panel on the fridge cabinet, halfway down the door. The rear slide-out control, however is set at ceiling height on the same cabinet panel, which is a bit of a stretch for some I'd have thought. Have to say that the rather bland looking interior beige colour scheme was, well, a bit bland for my tastes and I've certainly seen something more colourful from the Sunliner team. Lighting, though, is very much in keeping with Sunliner: There are reading lights, downlights, touch lights and concealed strip lights fitted everywhere and the main control panel is, as usual, well laid out. 

Lounging Around

Up front both cab seats swivel, although being an Iveco with its less-then-great handbrake location, turning the driver's seat is a bit of a wrestle. Additionally, the slide-out panel does block the swivelled driver's seat. The dinette is covered in matching upholstery to the front seats, occupies all of the offside slide-out and seats four, which would be a bit squashy. 

There's plenty of natural light from the large window, as well as night light from the considerable assortment of LED fittings. Above the passenger seat is the mounting point for the flat screen TV. Given the relative positions of the bracket and fittings it's a bit of a fiddle to fit, while seats with a good viewing position are a bit limited. In a way, the kitchen bench opposite might be a better option for the TV, with a stand, when not being used, of course!

Time To Eat

For the size of motorhome the kitchen bench area is surprisingly small. In fact the benchtop contains just a three burner cooktop, with oven/grill underneath, and a stainless steel sink alongside. That leaves space underneath for four drawers of various sizes and two overhead lockers, one of which is already partly utilised.

On the opposite side of the entry door, the two-door 184-litre three-way fridge, with microwave oven above, takes up most of the cabinet area. One of the upsides in this kitchen/dinette area is that the slide-out gives a fair chunk of interior space, but one of the downsides is that any storage space (for food and dining items) is much more limited. 

After Hours

An undoubted advantage of an east-west bed in a slide-out is it not only allows a decent bed length (1.9 m / 6ft 4in), it also provides a generous storage area, which in this vehicle includes both low and full-height built in wardrobes. The low cabinets directly opposite the bed are also were a stand fitted flat screen TV can be positioned. Having a slightly narrower bed (1.37 m / 4 ft 6 in) also allows for two bedside wardrobes, although it's a little disappointing that two mattress-level compartments weren't cut out at the base of the wardrobes because there's no room for bedside shelves. 

Keeping Clean

One of the features of the bathroom, with its nearside shower cubicle and offside vanity cabinet area, is that the mid-positioned Thetford cassette toilet looks like it sticks out slightly, which it doesn't. What its position does is allow for a good sized vanity cabinet, which includes a top-loading washing machine hiding under the cabinetry in the rear-corner, not to mention all round overhead lockers. Ventilation is courtesy of a fan hatch above the shower and the rear window. Both the bathroom and bedroom areas can be closed off by concertina curtains.

What I Think

If you desire a motorhome with an accent on space, particularly in the bedroom and bathroom, the Holiday G510 motorhome might well be for you. Certainly both the kitchen and dinette areas are relatively small, but there's no doubt having two slide-outs adds a considerable amount of living area to an already spacious interior. All that in a motorhome that is fully fitted out ready to hit the road!
