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.
I had the junk bumper replaced on my Komfort with a heavier one specifically to carry a bike rack, not to tow anything with. It's heavy enough that the stinky hoses won't fit inside any longer, though I never carried them there anyway. Welding shop rated the receiver, in writing, to 300 lbs, if I wanted to use a cargo rack, but said I'd almost certainly be OK with 500 if I really had to. As I'm now trying to sell the Komfort, I've not even used it.
