You should watch big rigs on the road. Do what they are doing, wide turns, slowing down early, etc.
Go to a parking lot with lanes marked. Center your RV in a lane. Put vinyl tape on the window so you know where you are when you are centered.
On unfamiliar roads...before you turn onto a suspect road, wait a bit. Park off to the side and watch traffic. If NO bus or truck goes up that road...move onto another road. Even if you have to wait an hour or more to see any traffic, do so.
Best advice though, is to really pay attention to what big vehicles are doing where you are. And follow their lead.
Driving a RV is NOT like driving a car. SLOW DOWN.
