Just got back from Hatteras myself. I have an 05 Hemi Limited. Even at stock height it worked flawlessly out there. Tried a couple of times to get it stuck in the deep stuff to no avail. QDII is a beast. As a 30 year veteran of the sand down at hatteras, the WK is far better out there than my '96 ZJ and I was really impressed with its sand ability.
A couple of notes:
-- I aired down to 23 pounds.
-- Turned Stability control off each time I hit the sand
If you dont turn off the stability control it will start going wild at certian times. I couldnt figure out what was going on the first couple of times since the ZJ did not have the traction control feature. Rather than have that thing sound like it was grinding my axels in half I started turning it off as I started out on the beach.
You shouldnt have any trouble.
