Ahhh. The question. I did say I would write one that very first day, didn't I? Well, I got cold feet and decided to read more forums to make sure I didn't see the answer to my question already answered, and waste someone's time.
I saw answers close to my Q, but not quite the same.
Anyway, when the AS arrived, it was missing one lug nut and that made me nervous to even tow the thing. I read the entire manual and couldn't locate what size to order to replace it. I did see a nice member post that included a photo with the nut and a decorative cover and discussions about those two things, just no size. If I don't see the size soon, I'll ask a local RV dealer who is going to help me pack the bearings.
