I'm surprised that the insurance companies don't require some kind of basic training for longer rigs. We started out with a 26' Class C and I was fairly comfortable driving it. Because that thing was such a pile of junk, we got rid of it and didn't get another RV for 5 years.
Between times, I came out of retirement (former aerospace engineer) and got a job with our local transit authority driving buses. The longest we had were 35' but they were a real challenge in city rush-hour traffic.
When we got our present 32' rig, I was very glad that I'd had the bus driver training, even though ours is front-engined and not a cab-forward configuration. The biggest challenge for me with the buses was making square turns so I didn't run the back wheels up on the sidewalk when turning right or cut the front end off vehicles waiting to turn right when I was going left.
I've seen many fender-benders where RV drivers have no idea how the back of a long vehicle cuts across a turn and doesn't follow the track of the front end.
As a Brit, that's my "six penn'orth".
