Welcome to the forum. I am not able to answer your question, but have a suggestion. You might consider posting this question in the Winnebago owners forum lower on the main forum page. Include the coach model, length, and chassis information. I'm sure there will be someone there who can properly address your problem and recommend a solution for you. I'll bet there is a simple fix.
