And I do another flat tow.. I have towed over two dozen different Jeeps many thousands of miles.. ALL were towed the same with out any problem EVER!
I place the tranny in 1st gear..then I place the transfercase in NEUTRAL.. then I'll start the engine and let the clutch out..this verifys the neutral transfer case..
and I tow it just like that! In these later model Jeeps the key must be in the on position to allow the front wheels to turn.. Older ones didn't need this.
In the daytime I unhook the battery. At night I hook it back up and turn the PARK lights on if I don't have the Jeeps tail lights hooked to the tow vehicle.
As most tow bars clamp or otherwise hook to the front bumper of the Jeep I check closely for all the bumper bolts to be in place and tight..If I attach a permant tow bar to a Jeep I always WELD the bumper to the frame).

Ps.. As you are in California and they have very strict smog laws I'd be certain to insist the Jeep passed and is current in inspections before purchasing a carbed Jeep in that state..In that state I wouldn't purchase a Jeep that didn't have fuel injection! Period!
