In the Netherlands it is very common to have dual fuel but most use propane
gas in Europe is $4 plus so propane cheaper over time and pays for the
conversion.
I would guess they have a propane kit just for the vanagons ready to go last
I heard kits cost about 1k. The engine is started on gas and transitions to
propane when the exhaust is hot enough to convert propane to a gas state
You do loose some power on both LNG and propane. I build lots of engines for
the ice resurfacer Zambonis they have air and water cooled engines most have
been set up to run on propane others are running LNG. The LNG is compressed
into a liquid and that can take hours to fill a tank. Some local towns here
in Massachusetts have LNG police cars and light trucks.  They have had to
find outdoor parking for them as they can not be parked inside just in case
they spring a leak. One shop in Arlington Ma. is replacing heads on a
regular basis on the LNG trucks so they tell me the seats are not hard
enough same problem I see in the Zambonis. The Olympics in Salt lake City
had LNG Zambonis between the LNG and the mile high altitude they where down
almost 50% on power compared to a gas engine at sea level. The local gas
company paid for the Zambonis what a surprise
