Motorhome Fuel Consumption
How long is a piece of string?
When we eventually sell our apartment in Spain, we are thinking about switching to a slimline MH about 6M max 3500Kg. Can members with similar weight/size MH's give me an idea of average fuel consumption so that I can compile some data to work with? Thanks
in advance or 'march has grass ears' as they say out there.

My old 'Wayfarer' with its petrol engine only gave about 25mpg, but my current Romahome R30 2.2 Diesel gives around 36 mpg. This is probably a bit smaller than you're thinking about, but I would expect most modern compact vans to give in the low - mid
30's.0 -
Peugoet boxer compass 200 coachbuilt 5.9 meters long 3 meters high
2.0hdi engine remapped to110hp
3000kg we are getting around 30-35 mpg

We average out 35 mpg, coachbuilt motorhome 3500 kg under 6m on a mercedes sprinter auto, 2.2 diesel.
The same as Brue except ours is 6.4m and we drive it hard so 25-30mph.
Like all vehicles, CY, the mpg depends on numerous factors.

We have averaged about 25 mpg in our Bailey 740 which is quite a bit bigger than the size you envisage. It depends what you currently tow with but 25mpg is a better than my previous towing economy although my towcar was an auto.

Type of body, I would think, as opposed to length has the most effect on consumption (assuming 3500kg). Big overcab designs aren't very aerodynamic and an A class is a bit like a brick. Width too will also play a part with Bailey offering some of the widest.
Low profiles and PVCs will give the best results as will a small shoe size and whimpy leg muscles. My 2.3 130bhp Euro IV Fiat Ducato always returns in the high twenties with up to 32mpg achieved quite often. I usually run at around 2250RPM which is slightly
quicker than HGVs. I have even achieved 27mpg towing a 900kg car behind. Figures quoted are from dashboard computer and I use cruise control at every opportunity, which is virtually all the time.0 -
Probably 28-30mpg.
Coachbuilt with overcab will give you c27mpg, a low profile coachbuilt 28mpg, an A-class 29mpg, and a PVC [Panel Van Conversion] 31mpg. This assumes you would drive as carefully as a sensible caravanner tows. I would allow 2mpg either side for variations
in your driving style.Individual journeys would give you a variety of fuel consumption depending on weather and route. I do 25- 27mpg west to east over the Pennines and 27-32mpg going the other way!

CY,our 09 plate Renault Master 2.5 dci lwb high top PVC ,3500kg with manual six speed box returns 33/34 mpg consistently on long runs at 2000rpm /65mph-this over years of ownership.An annual full service is £186 at our local independent garage(air filter,oil
and filter and fuel filter included.) Hope this helps.0 -
Thanks for all the input, folks. PVC's seem to be the least thirsty but I am wondering if this is due to some of them not being hi-tops. I currently get around 30mpg with 1350Kg van behind a 134BHP Kuga but this reverts to 40mpg once on site. With a MH I
am not going to get that "rebate" upon arrival unless I do a lot more pedalling than I am used to. Another consideration for the evaluation matrix.0 -
Too many things affect motorhome mpg - in my opinion, these are....
1) Height - some are 3.5m high - these will burn a lot more fuel than a 2.85 low line
2) Speed - chin up and foot down burns more than ambling along at 60
3) Weather - a strong head wind can knock our mpg to the late teens.
That said, the present van, having covered almost 10000 miles in nine months, has averaged 27 mpg, 5000kg six wheeler van, driven with respect.
I do not feel that weight affects it. OK, a 5000kg van will likely burn more fuel than a 3500kg version, but whether our van is packed to the rafters or lightly loaded, it matters not, hence we always travel with full fresh water tanks.
In my view, a low line, 3500 kg model, manual, six speed, driven with respect, aim for 30 mpg. On long motorway stretches, we can get 29 mpg on our lump.

It is nice to have a low fuel consumption figure but why buy a motorhome if you are worried about consumption? Other consideration might be the saving on road tax as compared to other vehicles and this can be used to off set some of the higher fuel consumption costs.

I wouldn't say I was worried but it is a factor to consider in evaluating the benefits or otherwise of changing from a caravan.

It is not a factor I would consider CY, there are much more important factors. Fuel consumption was not one I considered when moving from a caravan to a motorhome or for that matter,road tax . In most cases, unless you are buying a very big motorhome e.g
an American RV, consumption is on a par with tugging.peedee
