So all in all I do find the warning they give about heat and cool changes are very true, I think when we are in it full time and regulating the temp effectively it will be just fine, right now it is unoccupied and unheated to goes from -10 in winter to 30 in summer, its been in 1.5 years now and still looks and works great. It doesn't scratch, but holds up pretty well. I vapour barrier under it as well for waterproofing, but am not certain about the spots it has separated, gottabe carfull I guess!
Hey! Sorry I have not been online in a long time haha, not sure if this will be helpful to you now but here is our experience.
I did the whole floor, wall to wall, most of my furniture is connected to the walls, a few items needs to go through the floor. I also used the flooring on some walls as accent.
I've been pretty happy with it, I do notice decent shrinkage and expansion, during the summer we need the keep the windows covered as too much sun through the glass on the floor causes a lot of expansion and ends up with big bubbles, they don't hurt the floor and when it cools it goes away, seems to only happen when the bus is sealed and left and get very warm.
The shrinking and expansion has caused some gaps to come up, they are mostly in places we had trouble with install in the first place and maybe didn't get it locked in perfectly, which is annoying and troublesome to fix, but it is minimal and I think a cheaper flooring would be even worse!
