Just looking for other perspectives on a flooring installation in case there's anything I'm overlooking. I'm almost ready to install the flooring in my cabin. I'm putting down 7"x48" LVP click-lock planks with attached underlayment. It's going in over OSB subfloor.

There is one section of subfloor that was replaced and is about 1/16" higher than the rest, so I'll get after that with some 50-grit to smooth out the edges to make it less pronounced and take stress off the joints. The rest of the original floor has adhesive residue from the self-adhesive vinyl tiles that were on it before, so that will also have to be sanded off. I'm considering adding a 6-mil vapor barrier, but I don't know that it's really necessary with the attached underlayment.

The cabin is 12x16. I might consider installing the planks parallel to the 12' side to lend the illusion of it being wider, but going parallel to the 16' side means fewer cuts.

Any thoughts? Things I'm overlooking? Things you'd do differently?
