It is basically down the whole driver side. And they are not small ripples, they are waves that span about 4-6 feet... so it looks like the walls are bowed out... bow out in sections (of 4-6 feet). I took a 6foot level/straight edge and found the waves to have an offset of 1/2 - 1 inch in a 4-6 feet span.
I plan to go to local dealership and take a look at the Rubicons on the lot and see if they also exhibit they same thing. But like I said, it's only the driver side that have this issue. The passenger side isnt perfectly flat either, but any waving there is very subtle.
