Ask most motorhome manufacturers to deviate from their strict standard specifications beyond requesting different upholstery or perhaps a towbar, and chances are you’ll get short shrift. 

Time is money, and no manufacturer wants to interrupt valuable production schedules just so that Mr and Mrs Miggins can have their new motorhome built on a Chevy V10 base vehicle and kitted out with hammock beds and fluorescent orange carpets.

However, there are companies out there who will, within reason, grant you a surprising amount of latitude – if your bank balance is up to the job. 

One such is RS Motorhomes in Harworth. And while you’ll probably still have to whistle for your hammock beds, RS will happily accommodate rather more sensible demands.

RS originally made its name selling gigantic coach-sized RVs to devotees of motorsport, and its show models regularly had garages fitted with either tyre racks and compressors or a dinky little Smart FourTwo. And, while the company still specialises in this rarefied end of the market, it is gradually beginning to focus an increasing amount of  attention on more prosaic machinery; albeit still with a weather eye on that all-important subject of accommodating unusual customer demands.

And this latest Endeavour is an excellent case in point. Straight away, the Iveco base vehicle stands out as being something a little unusual. In this particular iteration, the R230G, it’s the latest 3.0-litre turbodiesel LWB model, packing an automatic gearbox. This may improve driveability (in the case of this particular example, it’s an essential upgrade, more on which in a moment), but necessitates the 170bhp engine rather than the 210bhp unit you get with the stick-shift manual.

It’s certainly an imposing beast, with a huge bespoke GRP body that’s so vast as to almost dwarf the not-inconsiderable cab up front. In fact, you could argue that this sort of XXL-sized body really ought to be on a tag-axle chassis: that rear overhang looks as though it could be a bit of a handful should its new owner ever have cause to board a cross-Channel ferry.

However, it certainly doesn’t feel unwieldy on the road and there’s no sense of rear-heaviness or wayward handling, even when you’re being passed by lorries. Much of this good behaviour can, we suspect, be put down to the fact that, all-up, this behemoth weighs in at a cool 7200kg – that’s just 300kg shy of what most B+E licence holders can legally drive without taking an additional test – with a fair chunk of that payload no doubt allocated to the simply gargantuan rear garage. In this particular instance, it’s equipped with ample lighting, a smattering of lashing points and grippy flooring. Rest assured that there’s room enough in there for all manner of gear – even a mobility scooter.
