The extreme temps and bouncing would concern me. It sounds like moisture isn't a problem and doesn't cause any change. Hiding the tape around the edges might mean you have to install trim? We do have some flooring experts and hopefully they'll chime in. I doubt the pros would use this product in an rv.
I've use the Vinyl (lock type and stick type) and have had a couple seems open up in the RV. Could be my fault from not using enough pressure rolling the seams? Good luck.
