Fuel tank size?

Don't you just love motorhome manufacturer marketing people. They build a lovely website which even has a boring footnote explaining that MIRO includes a 90% full fuel tank, but nowhere do they state the volume of the fuel tank. Not even in the part regarding 'tank sizes', which seems to be reserved for water tanks only. As any van will usually run with full fuel tanks at some time, it makes sense to know what they'll hold and how much of the available payload they'll use after a fill up.

Good point, I'll find the answer interesting.

Do you want to know the washer bottle capacity as well?

It is  only 9 or 10 litres extra so 7-8kg, and soon used up anyway. Less than the wife's handbag probably.

I think I've read somewhere that Boxers/Ducatos/Relays can be specified with two different size fuel tanks, one of the two options being substantially more capacity than standard. 

Presumably from Peter's answer the one fitted to A/S vans is 90 or 100 litres and I'll be able to make due allowance in my weight spreadsheet, so I have an idea of the potential maximum Payload we might be generating.

My wife's current handbag doesn't cause me concern but the driver being 35kg above the MIRO allowance does, as do two Beardies that weigh 45kg between them, plus their paraphernalia.

Hi Andy. There are three sizes of fuel tank available for the Boxer etc. The standard one is 90 litres, and optional are 120 and 45 versions.

Don't forget that the weight of a litre of diesel varies with the grade you are using.  

Petrol is lighter than diesel so perhaps better to fill up with that instead ?

Did that once with our Transit, back in 2007, and I wouldn't recommend it.

I blamed Shell because, at the time, I didn't realise that they marketed both petrol and diesel under the V Power branding. From everything I'd scan read I thought it was just produced in diesel, so I pulled up at a V Power labelled pump and topped up the tank to give it a try. Unfortunately it was a V Power petrol pump. Five miles later I called out the AA, was towed to a garage where they drained the tank and system. Luckily no other damage to the engine, cat. etc. Just a hefty bill, including refilling the tank with diesel again.

Thanks for the info CV.

Yes, standard Boxer is 90l, MB is 100l. AS won't be ordering non-standard.

I already had a spreadsheet set up for the weights of my car/caravan rig. I copied and pasted it onto another page and then set about modifying it to work for a '16MY Nuevo ES. I amalgamated the car and caravan's payload items, threw out lots of stuff that isn't necessary with a motorhome and otherwise used the same figures for the load items for both rigs.

The result - well the combined payloads of my Volvo V70 and caravan are 491kg, which includes 57kg of awning and associated gear. The payload for the motorhome (with no fresh water on board) is 375kg or a whole 116kg less. Do away with the awning and associated stuff and that difference becomes 173kg less to drive around. Obviously if I filled the fresh water tank to the brim that differential would drop to 71kg. It does make you wonder where all that extra weight is in caravanning though.

You are welcome Andy.

The rationale I imagine in the three sizes would be a standard average of 90 litres to suit most users. 

I can see the demand for a longer range tank for some transport operators. 

Not sure of the demand for a small tank,  maybe local fleet or municipal operators where vans are filled every night back at the depot, or to make fuel pilfering more obvious. Cannot see that 50kg weight saving would be more useful than stopping twice as often for fuel.

 Incidentally the Transit is 80 litres with an Special Vehicle Order 105 litre version.

Quite interesting the different manufacturers ideas really.
