And done right too—cut at an angle so they level out. It fits well with the front window. Down the road you can replace the quarter-round caps with light fixtures, or drill a mosaic of tiny holes in the stainless steel and put the light inside.
You put a trailer hitch on your trailer so you can trailer while you're trailering?
