Hi Noobie,
During the PDI on our trailer, I asked the tech if he thought we were being too picky. His response was that it was our silver pen signing the check. So we asked for everything to be fixed, including some minor cosmetic issues. Most of it wasn't a big deal.
On the other hand, I heard from another owner who had put their head on the bathroom floor to examine the underside of the vanity and found that it had not had stain applied (1" from the floor). He considered that a major defect and I think he may have even wanted the vanity replaced. Well, I guess we all have different expectations.
If there are some thing's bothering you but you're not sure if you're being reasonable, post your list here and ask - you'll get some opinions and can go from there.
