It looks quite good. Someone has done the conversion themselves or got a cabinet maker to build some cupboards by the look of it. I've heard nightmare stories about most of the european vehicles used for MHs as well as good reports so I think it is pot luck with any vehicle. It does seem quite cheap, but I think often vehicles are cheaper in WA than the East Coast from my observation only.
Makes sense that 2.4 typo could become 3.5, the next keys. Good luck with what you decide.
My 2007 is a 2.4 L 6 speed 6 berth Kea, weighs just over 4 tonne.
On a recent trip Adelaide to Darwin return I got an average of 12.99 L per 100k sitting on an average of 85 to 90 kph, once I push it over the 100 mark fuel usage rises substantially.
Seems to have plenty of power and will sit on 110kph with ease if needs be.
