I was driving one of those in the UK over 40 years ago. It was made by Hoyner, they also made car transporters. No more likely to fall over than any other artic tipper. I loved it, if you got bogged, you could 'walk' it out by alternatively braking the trailer and unit individually.I know the feeling with truck drivers. When I'm paving big lots and having alot of trucks running we start out with them all split up in the morning but by the afternoon I got 20 semis pulling in all at the same time, never fails. Lol. They are good guys, I just like pulling their leg from time to time.
