Bike rack on bumper failure

After reading so many posts arguing about the bike racks on the bumpers of TTs, I finally saw a failure today on the side of the road. They had a rack with two bikes on it, the bumper had torn around where it was welded to the frame, the bottom part was still barely attached. I don't know how far they drug the bikes before they realized it. I just saw it as I drove by, it was in the middle of town and looked like they had everything under control

We had a bike failure of our own. Same deal. Bought the racks online. Mounted them according to instructions. The welds tore loose after about 60 miles. Dragged the bikes down the street for about a mile before a passing motorist flagged us down.

I won't tell others what they can/can't do. As so many others like to do. But for me, I'll never put bikes on a bumper again. Ours go in the camper.
