We have some small ripples as well...some on our slide. I would not worry about it. I know you want the unit to be perfect, but there is always something. At least the ripples are only cosmetic. I would rather leave the ripples than let the dealer remove the trim, AC, vents, antennas...just to replace a perfectly good membrane and put it all back together. I think you could run into even bigger issues by doing all that.
