Regardless of the toad type...it's probably wise to check that the type bar, toe pins/clips & tow chains are connected, all cables are connected, brake system is OK, the wheels turn, the steering wheel turns in a corner, the brake/tail lights work and that the parking brake is OFF before you take off. You'd be surprised how many times the simple stuff gets overlooked. Just talk to the techs at a tire shop sometime.
It's certainly true that the 07 & 08 JKs have a steering column ignition lock so the ignition key has to be in the ON position to release the steering lock... Hence the need to pull the fuse to keep the battery from discharging. By the way, you can use a non-chipped key for this so that the engine cannot run.
