We watched our 36QSH be built in Feb. Absolutely a GREAT EXPERIENCE.
First, you should hope on the TiffinRVNetwork
to hear from other folks that have the 'Tiffin experience'. Not that you can't get that here. But there it is all Tiffin.
Anyway, we stayed at Jackson's B&B. But if you have an RV already you can stay at the Tiffin RV campground.
Get there early the first day of your build. You can see your chassis come in from the chassis shop. Then it will take about 2.5 days before your MH is driving off to undercoating and paint.
Visit the paint shop while you are in Red Bay. It's pretty nice, even if your coach isn't there yet. I'll bet you see a MH just like yours there anyway; including the paint scheme.
Take a lot of photos. It took about 465 and have notes on more photos to take the next time I am there. I have referred to them many times and they are quite helpful.
You can roam all over the factory. And you most likely will after the first day and a half.
All the workers there are very friendly. All are helpful and it seems they love to answer any question you have (and I had plenty). Toward the end of the build you can watch all the final inspections and are encouraged to point our things you are not sure about or think should be looked at closely. We asked for some molding to be changed, got a different drawer front because it didn't seem to match the others very well.
Have a good experience.
