Am considering buying the Mercedes 1222A currently listed on the forum. In good nick, it appears, and unusual in that it has a factory-mounted box already on it. Would like to keep it that way, but my question is, do I have to worry about torsion and therefore, lifting and placing the whole box onto some sort of torsion points? Not planning hugely aggressive overlanding, but we are talking Africa and some remote places in S. America. It's a 12-ton truck.
