We have the Allure lets call it "stick-lock" flooring. It looks nice and goes down pretty easy and is waterproof.
That said I would not use it again. We normally keep the temps around 75 whether in heat or cold climates but did go visit relatives where we stayed in their house and didn't keep the temps up when it got colder. The strips ended up separating in on the short ends. We just deal with it and call it a lesson learned. I ran it as a solid finished sheet (no breaks) front to back of the RV and into the bathroom and the area that separated is on the skinniest part of the run (about 5 planks wide in the hallway.) There is no amount of heat/stretching that we can do to make them come back together.
If I ever do this again I will be using a true click-lock (likely with a rubber backing) engineered hardwood product. It took 2 good days to install to cut around all the corners, angles, fixtures etc for about 4 boxes of the Allure.
