It's actually very well done. Wife and I went last year (did I say snow/mud!).
Pretty affordable. The classes (and there are a ton) are all well done (offroad/winch/photo/border crossing etc, etc.).
Plus, you get to check out all the vendor stuff. Sure, many are unoptainium, but others are affordable if in the market. Where else will you see all the stuff for overlanding in one place (not SEMA = mega-unoptainium).
If you never been, you gotta go once. Probably worth going every 3rd year or so.
Bonus: You meet really cool people that are aligned with your goals. A lot of knowledge rubs off from neighboring campers with lots of neat stories about roads/passages/epic non-published trips, etc.
