Just reserved our rooms at the "Grande".
To the OP, make sure you've got good recovery points front and rear and your own shackles, and it's courteous to have your own recovery strap. There's enough folk there with you on the trails that someone will help get you unstuck. Stuck vehicles are an event in themselves. The groups are divided up in the morning in order of vehicle build or owner desire to push it, so you can have fun with a group of folk with like vehicle build or desire for challenge. Chains are good to have along, as mentioned previously some years they are key, others not-so-much. I use the RUD's and have had good experience with them. FRS radio is good to have along so you can keep up with what's going on ahead of you.
Expect some scratches and maybe some dents and dings but always fun, and by the end of the day you will surprise yourself with the capability of your own vehicle. Lots of folk there with everything from lightly protected daily drivers to fully kitted trailer vehicles. All share the same passion for the brand. Great gathering!
