I would do it in a heart beat.
I have installed laminate flooring in every room in my house over the years and just finished the last 15 foot by 25 foot one.
I firmly believe that the spacing around the edges is a CYA thing by the manufacturers.
In some of the rooms I had to attach portions of the laminate to the sub floor for one reason or another and through winters where the house was left in sub zero weather with no heat on I saw no change at all
We have a 40 foot trailer which I will never move on a permanent RV spot, and I intend on installing it in the slide so we can get rid of the ugly carpet.
If I were hauling the trailer I would not hesitate to glue it down
What ever you do, don't by the el cheapo stuff. It is next to impossible to install ( from experience !)
