Mine looks similar to that when standing close up. From a distance though, it lines up pretty well. Stand back a few feet and see what it looks like... if it bothers you, take it in and have them adjust it.
As far as the shower, Is there caulk on the bottom where the wall meets the tub? On my G3 32BHDS, the part of the shower wall you see is a type of false wall for decoration, and behind that is the actual water barrier. I talked with Jayco about mine because the wall wasn't exactly flush and there was no caulk at the bottom, and they said that there was no caulk at the bottom because they wanted any water that did get behind that first wall to drain back into the tub.
