Congratulations Danny!
Getting Usable power to the bus for the first time is one of those things that make the conversion come closer to being in focus.
With one receptacle you have opened up a whole new world of options. After that first one though, you'll start to take the available electric for granted...... until something goes wrong, like trying to run an AC, a circular saw, a sawzall and a refrigerator all at the same time.
Plan well for the rest of your layout and it will eventually get done.
