Re the emission zone.

A friend of mine converts small vans in to campers, mainly used vans with 
new conversions and he has seen a big rise in people bringing petrol vans 
rather than diesel vans for conversions. He also said that the price of 
older coachbuilts are starting to rise and nom compliant diesels drop.

Does this mean that there are going to be lots of cheap bargain diesel 
campers around over the next 12/24 months or will no one be bothered. In 
Germany the equivalent of the LEZ has already spread to 4-5 cities will this 
be the same for the UK ? Some dealers already seem to be advertising the 
fact that once unpopular petrol's are now all the rage especially if you 
live within the M25.

Showing my inexperience in these matters but what was the reason for
favouring diesel campervans in the first place?

Probably cos most of the chassis campers are built on are vans with diesels 
for reliability and fuel economy.  It's only in recent years that petrol 
engines, once they got away from carburettors and into injection, became 
properly economical.  Diesel was historically cheaper and, with its higher 
calorific value  per gallon, gave better mpg.

No its about emissions.

Mpg when diesel was same price/cheaper than petrol

It is now, but the original question asked why diesels were preferred in 
the first place i.e. b4 emission became an issue.

There's not much in it for calorific value

but diesel engines are more efficient - largely because of the much higher 
compression ratios.

Most campervans are either converted panel vans or built on the same 
rolling chassis. Diesel engines typically produce less power but more 
torque than petrol engines, and they produce more of it in the usable 
range.

For example, my Volvo 850 2.5 petrol produced about 140 bhp and about 145 
ft lb. In contrast, my Citroen Dispatch 2.0 HDi produces only 95 bhp but 
158 ft lb and my 2.8 TD Pajero produces only 125 bph but 225 ft lb.

While power is what lets you go fast, it's torque that lets you move 
weight. So although neither is as fast, both my current vehicles will 
easily out-pull my old Volvo. Torque is more important than power for load-
carrying vehicles and makes sense for campers since they have permanently 
attached living equipment that takes up much of the payload of the base 
vehicle.

Diesels also have a much flatter torque curve, i.e. are at or close to 
max over a wide rpm range.

Modern petrol engine tend to peak at about 3500 revs and produce max 
power at about 5000 revs. Unfortunately this sort of detailed 
information is no longer generally published by manufacturers.

You on the other hand probably want to cruise along at about 60 mph in 
5th gear (at about 2000 - 2500 revs) and slow down or speed up without 
having to bother to change gear. The diesel is much more suitable.

I was considering to buy diesel campervan also because I could use the same
fuel from the same tank for heating or even cooking. Now I am bit uncertain
as what to do.

If you boycott London, or get something that complies with Ken's emissions 
limits, you can use diesel without problems. However, it's as well to be 
aware that Ken wanted to ban anything over eight years old from his 
kingdom, and when your camper gets older (8 to 10 years) it'll probably no 
longer comply.
