Thank you in advance

Having had a commercially built teardrop that managed to have problems with water along the wall edges in the galley, I've got strong feelings about this. I think most if not all commercial trailers fail sooner or later because water gets inside the walls. It's an area where us homebuilders can easily set a higher bar.
I use Raka thin epoxy (127?). Two coats. Epoxy is the choice for wooden boat builders. It's not that expensive and is easy to apply with a squeegee. I buy their pumps for measuring. Their three coat kit will do a drop. And epoxy the floor of your galley... sooner or later you'll spill something in there.
