no I've never used it off-road as I've been basically working on the bodywork and as this is my 1st Landy, I've been gradually learning about them and the workings of them inside and out (as you'll probably see by some of my idiot questions on these posts!)
as you say, if the MOD can cope with them, then its good enough for me...
i'm basically at the stage now where I need to spend money on things like, Tyres, Winch etc etc but I don't want to spend money doing these things if the power makes off-roading (when I come to do this) pointless + snow is coming so I need tyres etc for this
what do you mean by 'Tune up'??
