2016 Model 378, The kitchen sink with your design of small blocks of wood and a metal bracket has not held up in our 378. We took a trip to Yellowstone and the pounding of the roads caused our sink to drop. I reported it and was told I was to get some more mounts but it did not happen. On the way from Yellowstone to NY the sink got worse because of the extreme rough roads in Indiana. It seems the design of the sink brackets cannot hold up to traveling. The sink covers have a tendency to bounce slightly causing the brackets to fall out and allow the sink to drop. I placed some blocks under the plumbing pipe to keep the sink from falling down. The Blocks of wood and metal brackets you use are not satisfactory. One they come loose you cannot tighten the screw adequately to hold the sink it just come loose again. The distance from the wood to the granite does not allow enough screw to tighten sufficiently
So I went looking for something that would work permanently to hold up the sink. I found the “Never Fall Complete Sink Repair system” in which I bought and installed it. I don’t think I’ll be having any problems in the future.
