Everyone says "Daniel" is the hardest trail but the way your Jeep is built you can do it no problem.
Daniel was the hardest, well steepest anyway. It all depends on how long it's been since the USFS has graded the trails and fixed the water bars. There is a turn and small ledge on Daniel that can be fun if it hasn't been smoothed out.
Kodak Rock is on Rocky Mountain loop which is a small rock obstacle section, maybe 50ft long if I remember correctly. The rest of the trails are easy unless it's wet.
You may also want to take a trip up and down the outer banks while your there. Some pretty good scenery out there. Can take your jeep on a ferry ride, check out some lighthouses, etc. The part I like about the outer banks is the further south your are on them the less commercialized it is. You may find a CVS/etc on the north end where near the bridge across the sound but not south of there. Only access to the south end is by ferry or drive all the way down from the north.
