Just purchased a 22' travel trailer. Is a swaybar recommended?

Do We need a adapter plugs, surge protector and a volt meter?

EMS is essential in my opinion.

An adapter from 20 A (at house, for instance) to 30A at trailer could be useful, and perhaps 50A from pole to 30A at trailer.

A good multimeter is also, always a good idea.
