Sagging fiberglass skin around 5th wheel hitch

[Schade]

I have a 2007 Sierra 325RGT fifth wheel trailer that all the skin underneath the front of the trailer all around the 5th wheel hitch is dropping down I guess from heat and gravity after 11 years. Sagging so bad it has cracked in the rear corner and pulled away from the side for about 15” now. I am not sure how to support it. I have it taped up with clear duck tape. Has anyone had this problem? I am just now sure how to tackle this. Help

Preventive maintenance. Get it to a dealer before it cost 5 times more down the road. Sounds like you may have a small leak and it has rotted the wood under the fiberglass.
