Hello and welcome to the sabre family. Do not sit on this as water damage can be deadly to an RV. If they perceive you ignored it there could be some warranty claim denials. Contact a localhost river rv dealership and see if they can work with you. You can also try contacting Gary Grigsby who us the sabre warranty manager. If you haven't already done so, I would look into purchasing the 2nd yr factory warranty through forest river. It is $150. It was supposed to be purchased in the first 10 days of ownership but there have been others who had it approved farther out than you are. Here is the info for the second year warranty
Here is Gary's contact info

It sometimes takes him a few days to get back to you but he is very helpful as long as you stay nice and try to work with him too.
