Has anyone removed a holding tank from a C30? I must have incorrectly winterized it and it leaked this winter. The connections do not not appear to have any leaking or staining. So I am assuming it split internally. I have a 1990 model & have to replace it. I was hoping to make a factory replacemnt but it doesn't appear the old one will come out without destroying the material holding it in place. I still don't know if it will come out ,without it being cut up. Any suggestions will be appreciated. Thanks, Joe
