Do MH manufacturers make adjustments during the year?

I would consider looking at some other MH's. If they made such an obvious goof up, what else have they done that you won't find out about until you own it. There are other MH manufacturers out there. If price is an issue, find a slightly used MH that has good reviews. Newmar, Tiffin, and Winnebago/Itasca get generally good reviews. Of course I'm partial to the Winny products as I've found mine to be very well thought out. I have yet to find a "what were they thinking" on mine.
