Congrats on the new trailer ! Wiring seems to be a common complaint on these, We had the same complaint as well.I know you'll love it. Enjoyed ours from the day we got it.
I didn't get a chance to fix the wiring yet but I picked up some wire loom to clean it up. Spent the weekend installing a coat rack, vortex 2 fan and a max air 2 vent cover.
