Agree 100%. I used the glue down luxury vinyl tile (LVT) that was 4"x36" tiles in my last van. It was a glue down and the click fit stuff. I installed in the summer 70 something degrees and the next winter, minus minus cold the tile shrank about 1/8", enough to break the glue hold on some tiles. Terrible for getting sand in between the tiles.The vinyl planks you got may expand and shrink with temperature changes; you'd need to account for that when installing. They're not as lightweight as rolled flooring.
I"ll be using a rolled product of some sort that gets glue down this time.
