I have a 42 foot motor home will 3/8" tile in the kitchen I am thinkinging about a engineered wood floor. I am seeing all sorts of reasons why and why not. Has any body done this and any suggestions how to do it. Thanks in advance for your help.

Yup, lots of resons not to, mainly because the interior will nto be condidioned all the time. To hot, to cold etc. There are some nice wood looking resilient planks out there, even some on a click plank.

I thought engineered wood was basically like plywood, and more or less impervious to humidity fluctuations.
