I have a device installed called a Broquet. I have only just Googled it (After having my camper 18 months) and found that it is a fuel catalyser. See herehttp://www.broquet.co.uk/
If the hype is to be believed then a 10% increase in fuel economy, cleaner engine, lower co2 and particle emissions, from diesels, can be achieved.
Does any body else have one of these fitted and did they get the improvements mentioned. The device was fitted to mine before I bought it but my camper does go quicker and I can just about drive from the Lake District to St Ives on one tank of Diesel (going quite quickly too..)
I have never done a MPG test maybe its time I did.....wathch this space
