We used to go. It's a very large show but if you know what you are looking for, one day is plenty. When we were shopping for a MH years ago, I had it pretty narrowed to what I wanted to see (gasser, certain length, certain amenities, etc). It's really as simple as walking from manufacturer to manufacturer and walking through their offerings on the type of RV you want to see. There's usually only a few that each brings in a certain segment. It's pretty easy to tell when you open bin doors, look at seams, inside cabinets etc, what sort of quality you are dealing with. Prices aren't much better than a typical day at a dealership. Those "SHOW PRICES!!!" are really a marketing gimmick. You can always get the show price if you know how to negotiate. But it's a great show to see a lot of competing inventory in one place. Nations largest? who knows. Define largest.
