I would not recommend gluing them down as some have mentioned. Our temperatures are too extreme here in Canada when the RV is in storage. Good luck finding a glue to glue them to each other, but if you have no luck in the end you may need to find another brand with a better "click together" design. I've seen the self adhesive vinyl plank flooring used locally in cottages and after one season, the cool winter temp's cause each plank to contract allowing black glue to show at many or most joints They never come back together when brought back up to warmer temps.
