Keystone Sprinter Bumper

I have a Keystone Cougar and our rear bumpers probably came out of the same bin. My bumper is attached to the standard bike rack supplied by Keystone and the spare tire is bolted to the bumper.

My bumper has heavy cracking around both frame attachment areas. The welds go all the way around and are good-it's the bumper itself that is failing. I can no longer carry the tire until I get some repairs. When you figure out your solution you might also consider replacing your bumper with something heavier.
