Thanks Pairoa, I understand that they are not so efficient at high altitude, but it is compromise for we are prepared to make. We have heard from other users that their diesel stuff works even at 4000m, just not as well as it does at lower altitude. We are planning to drive around the world, and LPG may not be available in parts of SE Asia, Africa etc. We will always have diesel though. There are not so many places on our itinerary that are over 3000m high. The cabin and engine heater are the key things we need in cold areas ( Norway, Sweden, Siberia, Alaska etc) , the 9kW diesel furnace is the most important thing there, as we will need to keep warm, coming from Queensland where a cold day when it gets below 15 degrees C
It was a difficult choice, and we looked at loads of option, even metho/petrol stoves but the diesel seemed simpler. We even considered a generator and going electric with big batteries, but just can't live with the noise of even a "silent" generator and there is a limit to how many batteries we could fit.
Doing all the research and design is all part of the fun of building a truck, getting it right for every circumstance is difficult, but we are trying to think of everything.
Running LPG comes with it's own problems, and loads of regulations and rules over here. Your installation needs "licenced gas fitter" approval, CO gas detectors, minimum permanent (ie non closing) ventilation requirements. We will run LPG in our outside kitchen, and have a gas barbeque as well. They are all portable and if needs be, we can just buy a new stove and gas bottle in the local shop to run whatever pressure or fittings required. It is a lot more difficult to get a permanent installation to work in multiple countries. Things like regulators and jets might need to be changed, and the gas bottles and fittings are different. There are also different regulations depending where you are. Nothing insurmountable, but not something we want to have to consider at each border crossing.
