The screws that hold some of my under carriage bay storage doors are loose and can't be tightened. It seems that they are screwed into wood and the wood is rotten. I have a 2003 Coachmen Aurora. First, is this wood the floor decking to the RV because it's right at the floor level? Second, Any ideas on what should be done to fix? I hope I don't need to replace flooring Finally, has anyone removed the door from the coach? I can't figure that out. Thanks for any help.
