I have a 305 vret 5th wheel that has a problem with the bedroom floor. When i step towards the front of the trailer the floor creaks and i like to know how i can fix this without tearing up the carpet . this is not just in one spot, it's about 3 ft long. I know trailers are put together very cheaply as i have had to fix my refridgerator door panel and my platform bed. Now i have to deal with this too. Any suggestions would be greatly appreciated. Mike
