I got in the habit of checking trailer lights and brakes for every trip after I found that some yutz had run the brake wires for our 2023 travel trailer directly between the frame and the axle. Apparently I had bottomed out going over big bump on one trip and the u-bolt neatly severed the wires while leaving a little dent in the frame. Getting ready for the next trip, I was scratching my head why I had no green light on my brake controller and no trailer brakes, but the lights worked. Got to spend 20 minutes crawling under the camper doing some battlefield repairs in my driveway to splice them and zip tie them out of harm's way.
