I have installed Pergo plank flooring in two different motorhomes. It is intended to be a floating floor but because of the continual shifting of the motorhome I decided to staple the perimeter.
The first motorhome I did I owned for another 6 years after I installed the floor and had no problems with the floor. Still looked new and was easy to clean. The easy to clean part is important to us as almost all our camping is boondocking and tracking in dirt and mud is unavoidable.
The second installation is 1 year old now and no problems with it either. See the attached photo of the installation process.
I live in Colorado. When in storage the interior temperatures have ranged from a few degrees below zero to about 120 degrees above. These temperature extremes have not caused any problems.
Caution, if you have slides that will slide in over the floor you must be sure that the new flooring is not thicker than your current flooring or the slide will drag on your new floor. Now that would be a drag! :(
