Congrats.

You should have lots of fun with it.
If you need bearings or a hub for it I still have them from the old axle that was on my trailer before I had an axle with brakes installed.
To keep from slipping on the trailer tongue when it's wet I stuck on some non-slip stuff, looks like course sandpaper.
And tie up that cord for the plug so it doesn't get caught on something in the road.
Tom.
