I have hitch on my Cedar Creek, came from the factory like that and guess what the weight was on the hitch, 50lb. Can you believe that. I plan to cut off that hitch and bolt on another one on. Cedar Creek says that will void the warranty but I own the camper now, one year warranty is gone
I was behind a fifth wheel that had a bike rack mounted with a couple of bikes in it and every time they hit a bump the bikes had to bounce 8-10 inches. With as much flex as the bike rack had and the amount of bouncing that was going on back there it does not surprise me that it may cause frame damage.
