I am sorry for your problems with your Cedar Creek. But that is why I bought locally so, I could get warranty and parts from a local dealer. I know I didn't get the lowest price from the dealer but I can get service which I have received from them.
Have you tried the Forest River web site to find a dealer in your area that you may order parts through?
If not this link may help you! All you need to do is change the model name you are looking for.
