Honestly, I think you'd be ok with any type of TAD. Hell as long as you've got decently wide tires(no 33x9.50s

) and air down you'll be fine. I've seen Subaru Outbacks on the beach at Oregon Inlet do fine. The key is knowing how to adjust your driving for the sand. You have to be real gentle with the throttle off the line, but once you get going, keep it pinned to maintain momentum and wheel spin. Similar to mud, but a lot less forgiving. Basically, since it's only a few times a year, you don't wanna build a sand rig(paddles, big motor, etc etc) so just run whatcha brung and you'll be fine.
