My first fifth wheel...my first rubber roof. No bubbles of any kind on mine, but it certainly isn't smooth at some of the seams and on the sides where it is fastened under the metal banding...it has many puckers in different places on both sides. But, hey, I'm a fiberglass roof kind of guy and I feel comfortable with them. When in doubt, take some digital photos and document it with keystone before the warranty is gone. If it is already, then share some pictures on the moc and see what others think. John
