How to secure a residential drop-in bathroom sink?

I am considering replacing my existing plastic bathroom sink with a china one like this which is a perfect fit:

https://www.homedepot.com/p/Glacier-Bay-Aragon-Self-Rimming-Drop-In-Bathroom-Sink-in-Bone-13-0012-4B...


The existing plastic sink has clip mounts around the underside of the sink to secure it to the counter which is laminate/particleboard. This sink will not have that and the instructions say to just put sealant on the counter before dropping it in. This might be sufficient, if you use a construction adhesive like a Loctite Power Grab, but I don't think just a sealant would work in an RV. I could fabricate a piece of metal with a hole for the drain collar that would wrap up to the underside of the counter.

Do you all have any ideas?

thanks,

X4....Just did a household sink the same way. Lay it in a good bed of silicone caulk/adhesive (clear or white as appropriate), let it sit for 24 hours (don't get tempted!) and then hook it all up. You will be good to go for many years to come.
What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?

Just like ScottG said, silicone will work just fine...
But, if you want to bomb proof it, use a 2 part epoxy....like Loctite or JB Weld.

A sealer/adhesive should be able to hold it in just fine. Remember to wait 24 hours before attaching the plumbing.

Glue "L" shaped metal tabs to the underside of your sink and screw them into the underside of the counter

and if you are still worried get some plumbers strap and run in from side to side and secure it under the counter top. Let the silicone set up first tho

After installing, remove every bit of visible silicone for a clean, tight job.
