Leak where grey water drains connect to the grey water tank

[mspoe]

I have a 2012 Georgetown 378 that has been in for warranty work three (3) times. I have dewinterized and hit the road only to find the leak still present. I am now in Albuquerque at American RV Park and called Joe at Travelers RV Mobile Service. Joe isolated the leak to somewhere behind the wall in the bathroom where all of the sink/shower drains connect to the grey water tank. A dealer in Missouri charged FR three times for warranty repairs for this problem. I am calling Justin at the FR Georgetown factory to initiate a charge back to the Missouri dealer for the warranty charges and looking for a reputable repair facility in Boise, ID to take it to.

Has anyone heard of a FR recall for this situation?
