Gosh that would be some motor, I would reckon you need a tanker behind you, a lot less mpg than autotrail

I believe it to be about 8-10 mpg.tonka said:Before I go off and spend hours looking at RV's..
Can someone advise what sort MPG can be expected from something like a 6ltr Diesel engine..
Considering a short vehicle no more than 30 foot, not sure if this will make much difference ref weight etc,,,
Currently got an Autotrail and keep admiring the American RV's

I was able to make my mind up with that one sided list of pros and cons:tonka said:Cheers all, for replies...
Have to give this some thought and do more research..
Lots of pro's and con's to consider...... :?
Thanks Dougie.asprn said:My 6.8 litre V10 petrol 32-ft RV achieved 11.5mpg to the south of Spain & back last time we used it, whilst towing a car on a trailer. What changed my view completely about fuel consumption on RVs when we were considering one, was this:-
I got 24 mpg towing with my previous 2.5L turbo diesel Peugeot engine. Calculate the difference in cost per gallon, and calculate the extra cost per 1,000 miles. So, taking a gallon of petrol as £4.36p, and a gallon of diesel as £4.68:-
1,000 miles @ 24.0 mpg = 42 gals = £196.00
1,000 miles @ 11.5 mpg = 87 gals = £379.00
Extra fuel cost per 1,000 miles = £183.00
We've averaged 3,500 miles per year since we got the van, which means we've paid £640.00 per year extra in fuel. For what you get in terms of paradise on wheels, it's been well worth it, in our opinion. Others may disagree, but there you go.

From what I understand from other RV owners, not towing will potentially give you another 1-2 mpg. I would doubt the extra capacity would make any significant difference, but coupled with being a diesel, it may provide another little bit.alexthecheese said:I know it's hard to say, but with the extra capacity but reduced load (not towing a car) would it be fair to expect similar mpg from a 454 7.4 litre Chevy engine with 26 foot motorhome?
Thanks Dougie. What I'm looking at is also a petrol, so would hope to get similar MPG. It is already LPG converted so that is very much a bonus.asprn said:From what I understand from other RV owners, not towing will potentially give you another 1-2 mpg.

Duncan (damondunc) is the font of all RV knowledge, and will be able to provide you with facts and figures based on experience. Might be worth PMing him.
