Looking to buy a Georgie Boy Landau 6.9 ltr petrol V10
Anybody any ideas on how much a gas conversion is?
Dealer is advising 8-10 MPG is this correct?http://www.motorhomefun.co.uk/images/smilies/blush.gif
I have the georgieboy pursuit 7.4 v8 vortech
it cost £2500 for the lpg with a 175ltr gas tank fitted in 2008 by previous owner
yes 8-10 mpg on gas

not worth doing if you not doing moon miles
£2500 is alot of petrol

Having run a much smaller engine on lpg, with the increased cost of lpg I agree with the previous comment it just doesn't make cost sense, even if you have lpg fitted the reduced mpg you get weighed against the increased mileage on petrol the price difference is often barely discernable.

Just did a price comparison on petrolprices.com for the Ipswich area. Diesel around 135p, LPG around 70p, that's as near as dammit half price. So even though you may get 10-20% less mpg on LPG, "IF" (and that's the question) you do the mileage then its worth it. For us it was easy, we knew we would be keeping it a longtime.

Our conversion was £3k and I consider that cost as part of the initial capital cost of the RV We have 10k on the clock in the two years since new.
Did 2k miles in Spain last winter at 10mpg on lpg and it feels so much better paying just 65/ 70p a litre when filling up.
I think with an RV always worth it to convert :thumb:

Hi I have had a couple of LPG cars and in effect you are doubling the mileage (money wise)mpg IE on my v8 LR Disco 15 mpg on petrol gave around 28 mpg =£s spent on gas-gas being half price.If you are buying a RV to convert to gas then it takes a long time to get payback :Smile:Better to pay for a already converted LPG one that way you get the benefit and somebody else stands the cost ::bigsmile:

I think ... it's kinda like two virtually identical houses on the same street where one has been recently double glazed and the other still has the original or older double glazed windows. Or better/newer central heating or whatever. Makes the first house better value for the same price.

But would you pay an extra £x thousand? - no ...... perhaps a couple of £hundred, depends.

things may have changed over the years but my V10 has two LPG systems running as one.

at the time of fitting there wasnt a kit available for a 10 cylinder engine.

i would expect around £2500 to £3000 today.

1996, then break 'til 2011
A bit late on this thread but unless I was going to do a lot of miles I would not pay to have a conversion fitted.
I owned an lpg converted Jeep for a couple of years, 15mpg, range on full 100L tank 225 miles - not a lot!
It became a pain even using it locally where I knew where the lpg pumps were - a nightmare trying to find lpg on the road (and I did have a map of lpg stations).
After every fill up I would set the 'trip' and start thinking about a refill after say 180 miles. It also takes an age leaning against the fill button to fill the tank, if someone is using the only bank of pumps that has lpg you have to wait for a space - on the right side.
Personally I would always prefer diesel - or just petrol if the mileage is low.
Motorhoming is about relaxing, watching the fuel guage (or trip meter) looking for lpg stations is not.
- My personal experience/opinion - if you know of anyone that has used lpg ask for theirs
Good luck with your new RV

Range, availability of LPG abroad, cost of LPG, all make this a "capital cost" equation, never one about runnign cost's.

I agree with he estimate of £2500-3000 with the installation carried out by a certificated dealer with experience of large volume engines. Persobally, i would also agree that it would be better to buy an already converted vehicle...but having said that, if you can suffer the cost....when you need to sell, yours will sell quicker.
LPG is never going to be a magic wand, but it may make the difference between buying or not!:thumb:

I have a petrol van conversion and decided to get LPG on it. Gives me the equivalent of 30mpg based on diesel cost.

The BRC system has so far proved reliable and easy to use. LPG stations can be a bit hit and miss, I found the Shell and WhatGas apps handy. Assume you can't run on gas 100% of the time, which is best anyway.


The cost of the conversion was more than offset by the saving I made by buying a petrol model when many others would have steered clear. A diesel model of the same year would also have been well outside my price range.

My previous RV had LPG conversion fitted when I bought it and in my experience unless I intended to do a lot of annual mileage I would not bother again. If it was already fitted, then ok, no problem.
The reduced cost of fuel was a bonus but as previously mentioned looking for lpg can be a pain and on many occasions I was unable to access the lpg pump due to its positioning on the forecourt. Having to put petrol in when you have lpg tanks breaks your heart :cry:

If you do decide to go for conversion try to include long range tanks and have a filler point on both sides of RV.

After 10k miles in two years LPG is the only way for me with a range of over 330 miles supply is no problem not even in Spain.

The fuel cost LPG = £3,444 the equivalent petrol cost on my RV would have been £6,150 , this is calculated allowing for a reduction in mpg for LPG.

A saving of £2,706. In 2 years the conversion is almost paid for :thumb:

By the way estimated diesel cost for this mileage at 23mpg is £2,773 (perhaps around right for a large MH ) for comparison mine weighs all up 6557kg.
