Tail swing is when the tail end of the RV swings out beyond the turning radius of the turn. The more length behind the rear axle, the greater the tail swing. Some Class C RVs have the longer wheelbase between the axles and a lot of them just add on extra length behind the rear axle. That means you have to extra diligent when making a turn, especially a sharp one. You need to watch your mirrors very closely, especially when in tight quarters like a gas station or a sharp turn. The rearmost portion of the vehicle can actually go outside your lane into the next lane as you make a turn.

My retirement job was a school bus driver. Every year when you were assigned a bus, senior drivers always looked for buses that had the least overhang behind the rear axle for this reason.
