She will do wonders!
Took my 4Runner down to Galveston a couple weeks ago. I have the basic SR5 package and at the time just some basic all terrains. My 2WD got me extremely fat I will say, I didn’t get stuck the first time although much of the sand was flat. It was right up on the beach though so it was kind of wet, but she performed great. A went back a couple days ago and did end up getting stuck. Both times I have gone my back right tire was pretty bald (I do a lot of burnouts). I think your T4R will get you where you need to be, especially with all the traction and 4wd stuff despite your tires. I would just refrain from super soft sand and hills. That’s where I got stuck the second time was a hill. When in doubt, throttle out. I would by all means though, suggest some simple all terrains. If you do end up getting stuck, grab some wood planks and dig a slight hole under your tires and place the planks there. It isn’t 100% trust worthy but it could save you! Have a fun adventure!
