Can you post a few pictures from under the sink, showing how it looks?

Undermount sinks generally use a combination of adhesive and sink clips to hold them in place. Some of our Allies have had their sink fall and in most (but not all) cases, they travelled with dishes, coffee makers etc, in the sink. The moment weight of material stored in the sink when the coach is bouncing down the road can be problematic.
That all said, I am not suggesting this is the cause for your sink failure. As @Oregon_Camper has suggested, please provide some pictures showing the underside of the sink where the sink edge meets the counter top bottom.
Here's a link to what various sink clip styles. If you were to DIY repair using new sink clips, be very careful as to the length of screw you would use to go into the counter top wood substrate. I think it's only maybe 3/8" thick.
Also, feel free to email your pictures, a description of what is happening, your name, phone and last 6 of your VIN to our service team at service@alliancerv.com.

I'm not sure what the factory uses. If I was doing it, I would use construction adhesive, then use temporary wood supports to hold it in place while the adhesive cured, then add metal sink clips.
Note, this is just what I would do and not factory service advice. If you want that, kindly reach out to our team at service@alliancerv.com

Use 100 percent silicone. You can also fashion clip holders out of scrap solid surface and crazy fly them to the bottom of the countertop. Yea crazy glue! Acrylic lives crazy glue
The glueing idea works I have used that method in the past.
However I came across these mounts on Amazon
and they work fairly well. See link below

Our sink fell down several times, glue will fail eventually. I bought this kit, then realized the innerds of the caninet wouldnt support it, so I added support boards and went ahead and beefed up the floor also.

Remove top. Flip over. 10/32 x.25 brass inserts. Use approx 16. Screws with washers and fender washers. Voila. Add silicone before screwing down and you can stand in the sink.first pic was the original four clams using waffle studs

This kind of thing wouldn't happen if manufacturers focused more on the suspension system than cutting costs. The roads, particularly the interstates are in terrible shape. Heavy trucks are destroying them as fast as they repair them. RVs need special suspensions with some kind of dampening, like shock absorbers, or something.
No doubt the roads are rough and rv suspensions could be improved
However undermount sinks fall, come loose in stix and brix houses.
It is a fairly common issue. Amazon sells a repair kit for undermount sinks.

If it were me when manufacturing the plywood would be cut so the lip of the sink rest on the plywood, I realize this is not a fix for the sink failure. This would require removing the sound proofing from the lip.

It’s really not that hard. I have personally mounted thousands of undermount sinks with not one single failure……..
I have not encountered a sink failure in one of my jobs. However several customers have called to say their sinks dropped where we did not do the original install. My comments are based on stix and brix houses not RV's.
I agree if installed properly sink should not drop however we know there is the human factor and everything out there is not installed properly, especially when it comes to RV's

Alliance is now using Lippert’s new helix pin box and TCS suspension. You can see it in Matt's video.
