"All the other makes, have already had that option in place, like stated, for years. You see, you need a 4x4 because, it's transfer case having a neutral capability, disconnects both the front and rear drive shafts so that when they spin, while you're towing it, they have no effect on the transfer case or, the transmission or, engine.
Now, I don't know what year you might be interested in but, in the Chevy and GMC, prior to 2013, all you did in prep for towing was, put the T/C in neutral, put the trans in park, release the parking brake and, remove the key. You're now ready to tow."
Fire up, another thought here sir.
When you remove the key, you lock the steering wheel. Am I reading this right? I have pulled trailers for a million miles but not a flat tow like this. Doesn't the front wheels need to turn (caster steer) as you pull it?
