Another thing to consider is how you get in and out of the truck. There are a couple of options.
Assist steps that can be used with rocker panel protection. The steps need to be removed before offroading. Not hard, just a couple of bolts.
Nerf bars. With nerf bars on you can't have the rocker panel protection. kind of a dumb set up. These have 4 bolts each to take them off. And it's recomended that they are removed before offroading mostly to keep from damaging the bar. If you leave them on they reduce you ground clearance by an inch or two. I have them on my truck but haven't tested how much abuse they will take.
If I had know about the assist steps when I bought my truck I probubly would have gone that route.
Another thing for offroading is an underbody shield. It's not included in the Adventure package but is probubly a good idea. Below is a link to what I'm talking about. The adventure package includes a shield for engine, trany and transfer case. But there's still a big area not covered. These will help protect that.
