I plan on getting all the connections ready and then having an electrician connected directly to the box. your thoughts would be appreciated.
Dirk has all the information you need in the link he posted.
I don't know who told you to use 3 wire but they are totally wrong. You need to use 4 wire, one RED, one BLACK, one WHITE and one GREEN. It also needs to be sized (proper gauge) for the distance that you are running it from and to.
The wire size calculator will do that job for you.
RED and BLACK are the two HOT legs, WHITE is the Neutral and GREEN is the ground.
Remember that your RV Electrical box is called a Sub-Panel which requires the Neutral and Ground to be separate not bonded together.
