I'm not posting this out of a dislike of 4x4s, we have had a few including a discovery which we liked but don't feel that just because you are towing with a 4x4 heavier than most cars they are invincible. Take it easy out there folks!
The following is from another forum:-
"About an hour from our destination on the first day, we were heading down one of the motorways. I passed a GB Discovery towing a large caravan and eventually passed a coach. There was a stiff headwind and passing the coach was a bit un-nerving. However, as we struggled up the hills the coach eventually caught and passed us again. I told my wife, I was just going to sit behind it as the buffeting was not fun to drive through, even in a large A class. For quite a few miles I just sat at a reasonable distance behind the coach.
Next thing the Discovery comes past us, and then starts to pass the coach. As the caravan caught the first blast of turbulence, it started to snake. In an instant it was out of control, with the caravan shaking the Discovery like it was a rag doll. The whole unit slammed into the central barrier and then into the coach. My family were screaming for me to stop, which I did just as the Landy jackknifed in front of us and into the side barrier. The occupants were trapped by the barrier on one side and the caravan on the other. I was just praying that the whole lot would not flip. I ran to the Discovery and broke the window and got the lady and her kids out. By that time a few other people had stoped to help and we bundled the family into a MPV and tried to calm them down."
