If the warranty was going to cover the tow which it did. Then it was the best option at that moment.
Note:
When you shut off the 4x4 trucks like mine. That it goes into 4x4 when off.
With the engine running the vacuum that's created helps to hold the axles back from engaging into the hubs when the truck is in 2wd.

That makes sense, is there another reason like that for the only 2wd? The owner's manual says to not tow the automatic trannys with the back wheels on the ground. They say to only have the front wheels on the street and have the back suspended or on a trailer. I've never understood why but dont want to find out the hard way. I'm guessing the truck never really goes into neutral like a manual does?
