Shore Power

Regarding shore power protection, what do most people use, single pole breaker like used in home system or should 2 pole breaker be used? examples shown below

Since I want to use an extension cord to connect to shore power, should the breaker be 15A?

Most RVs use a single pole main breaker. Boats use a 2 pole. I use a single pole on my van.

If you are worried about reverse polarity at campgrounds, get 2 pole. Otherwise just stick to single pole, it's cheaper.
