2017 T@B 320 Boon Dock: Cracked Pipe from Shower to Gray Tank

Hello Peeps,

Another year, another repair. My husband and I are getting the Little Guy ready for the season and noticed a big leak from underneath the shower. All this after sealing up a cracked pan. Ugh! We ordered a $30 scope off of Amazon, removed the pea trap and threaded the scope from the bottom and discovered a big crack in the pipe leading to the gray tank. We ran the scope for about 13-14 inches until we found the crack. The crack runs along the circumference of the pipe. Attached is a picture of what the scope captured. I read several other threads with the same problem, but was wondering has anyone actually repaired it without having to drop the tank such as threading another pipe or sleeve? If so, what product did you use and how did you connect to the tank? All suggestions appreciated.
