Because it matches the truck?
Yeah, I see the silver tow. But I would think some grand sweeping graphics in silver would have been a better choice.... unless there's some major damage somewhere and the owners were trying to cover up the repair. Of course, that's just speculation and it could be perfectly okay underneath.
However, I have been told all my "taste" is in my mouth.... so what do I know
Different strokes for different folks and that's what makes us (and our trailers) unique!
