Question for Forest River 5th Wheel Owners or anyone this might pertain to

We own a 2022 Forest River Columbus 379MBC, the other day I was doing dishes, the undermount sink fell completely down. It is no longer attached to the counter top. Has anyone ever had this happen? What is the fix?  It was only glued in with no supporting clips.

  • As you know, owning an RV requires you to be a handy man or have deep pockets. I am surprised the sink fell with the rigid trap in place to help support it. But your options are: clean the edges up and re attach with contractor adhesive and maybe add a few clips or brackets to keep it in place, or find a top mount. Top mount might require modifications to the plumbing to meet up with the trap. In either case you'll need to re-caulk the edges.
