Looking for dog breed the travels well while Rving

More critical than the breed is the dog's socialization very early in life to different situations.

Most definitely. While you can make SOME generalizations it's mostly up to you. Ran into a woman with a Springer a few months ago and the dog was not aggressive but not comfortable meeting new people. Mine will knock you over trying to get your attention. I'd be more concerned with temperament and personality than breed.
