I had a UK wide arch LWB man for 12 months.Did what it supposed to and comfortable,19-22mpg. Problems I came across with mine and on a good forum was.Fuel sender packing (easy repair) issues with the 4wd.The actuator seizing up through lack of use so you could engage 4wd but no diff lock I think.The biggest issue I came across was them starting and then stopping first thing in the morning then once run again fine.It pointed to the seals on the pump apparently on the 2.8 anyway.Have look on here loads of info and helped me
