Anybody have experience with installing floor tile in a Prevost?

Is there cause for concern regarding floor tiles popping off due to flexing of the coach, frame or floor?

We've got carpeting in living area, galley and bedroon and tile in Bathroom. Wife says all must go and new tile to be installed (by me) before POG III.

Could use suggestions and helpful hints regarding this project other than:
A. Change coaches
B. Find new spouse!
