Hello Roger,
the Jaxon is not a small car, its weight is full dressed about 120 Kg and with me 225Kg. With 1 Kg Propane I can drive between 6,5 and 7 Km far. The farest travel on a day was 14 km with 2 bottles of propane and about 25 liters of rainwater for steaming. A good addon is a not visible electric drive for a comfort home drive, if there is to less water or gas available.
I drove, since the first ride in august 2023, 586 Km till now. Since the first ride I made many improvements and the car was changed to a switchable compound drive for more speed and mileage.
There is now only room for refinements like a bigger oil reservoir for the cylinder oil pump. what I like to have is a display how many burners are active during driving. AT the moment I can only estimate it by the boiler pressure gauge.
