Jeeps are great on the beach!! I run a 2002 Jeep TJ, 6 cyl automatic. I put a 2.5 inch lift, 32" BFG All-Terrains, and a Lock-Rite "lunchbox" locker in the rear, and I have NEVER had any problems on the beach. With the locker I don't even need to use the 4 wheel drive all the time. However, the mods that I made KILLED my fuel milage. I don't use it as a daily driver so it's not that big of a deal to me considering how it handles in the sand.
