So just remove the rear drive shaft and make sure that the front hubs are unlocked. What about the steering? Locked unlocked? What about tow bar selection? Just the cheap A frame type? Thanks Again

You will want to leave the key in the ignition in the unlocked position, otherwise you wont be able to turn the truck.

If you are going to do a lot of flat towing, you might want to consider swapping in a full floater rear axle kit with hubs, then just unlock the hubs when you tow it.

More than tread lightly. Leave it like you were never there, nor anyone else.
