I agree. If you are going to run 4 wires, install the outlet and breaker that takes all 4 wires. Done once and finished.
That is what I did. I have a 30 amp RV. For now. When I ran my power, I pulled three 6g wires (black, red, white) and one 10g wire (green), put in a 50 amp breaker, and a box with 50amp/30amp/20ampGFCI outlets and breakers. I will never have to touch that wiring again, no matter what I may buy in the future. It did not cost THAT much more to do than a straight 30 amp setup would have been.
(While doing this, I also ran a second conduit and installed a separate box with telephone line and satellite/cable coax. Like I said, done once and finished.)
This is only code compliant is you have a 20, 30 and 50 amp breaker at the box at the trailer. Otherwise you could overload the 20 amp and 30 amp between the trailer and the box.
Note the part of my original post that I have highlighted in red.
Thank you
