Add us to the list of people that had the kitchen sink come unglued. During our last trip the DW noticed the right side had dropped down a little bit. Another lesson learned... had I seen this thread earlier, we probably wouldn't have run around all this time with one of the sink covers in place.
Anyway, thanks to this great forum for providing me with the information I need to go fix it now
I'm off to the store now to buy some 100% silicone glue/sealant and bar clamps.
