I am thinking of beefing up my sump guard so as to be able to enjoy off roading in the mountains a bit more. I know of the Mantec but quite frankly do not want to spend that sort of money on a sump guard when you can get such things for Defenders and Disco's for around £90! Why does it cost so much and why does no one else make one? Anyway has anyone modified their own? Chap did it in the recent Modifying your Freelander article in Land Rover owner international but no other info on it. Would the first step be to get hold of some fairly thick chequer plate material and try and copy what is already there and bolt it to the existing frame somehow?
