How old is your unit ? This would fall under the 5 year structural warranty. I had a floor issue in our bedroom slide at 4 years old and Redwood took care of it. I will say however, that even if it is a long tow (for me it was 650 miles each way), schedule it into the factory service center and have it done there. I wouldn't have anybody else do it.
