The metal ends are a bit too thick for both truck and trailer. I will have to grind them down with my angle grinder in order to make them work. Other than that, the lights do come on, but they don't fit in all the way so the latch isn't locked. I even tried putting 5th wheel grease on the sides and beating it in with a rubber mallet, but still wouldn't go.
