that would **** you off to say the least reading your link
indeed. I read a good post on another forum regarding overland use and roll cages which gives good reason to ponder. Anyway 2 scenarios were put forward:
1: your on a big trip, London to Cape Town for example. your travelling through Morocco, 2 weeks in, you drive some dunes. you cock it up, your landy is a big mess and if your lucky your ok. what happens next? your plans are ruined, you have to return to the UK and you have lost/wasted lots of £££ and time.
2. same thing with a cage. a few weeks in, or a few months in, you roll over. some panel damage, wings maybe, hopefully engine is ok. locals may be able to put it straight enough (and safe enough) to carry on. The trip proceeds (at some extra cost) almost unhindered.
In my mind the advantages for this kind of travel outweigh the disadvantages. The other selling point for me was mounting the RTT. It fits directly to it, no expensive Alu rack, roof bars, worry about roof weight limits etc.
