Lay vinyl in a double wide trailer over the marriage line?

That marriage line has to be dealt with one way or another. .. If there is a slight unevenness there , a filler, of some kind must be used. Then ,if you go with a vinyl you must use the thin ply ( 1/4" luan) and then the vinyl. Not doing so that line will telescope thru and show like a sore thumb. It could possible tear the vinyl at that point if there is any move ment.The perimeter bond or glue less vinyl will still need the under layment because that to can show a line thru the vinyl from walking there. Laminate is a good option too, like the guy said. As long as there is no large evenness ( still will have to be filled w/ something if theres unevenness.
