That's too far out of my area to know much about it, but I would think having it towed to Elk City would be the best bet. There are better hotels and of course more mechanics to chose from.

If the engine is fried and needs a new one Oklahoma City is not too far away. One could be delivered to Elk City in a few hours.

The only other logical thing to do would be to rent a U-Haul and tow it home or to drag it over to Amarillo. Once you get five miles off either side of I-40 you just drop off the edge of the earth.

She could also have it towed into Shamrock, Texas which is a bigger city than it looks like on the map. They also have some nice hotels there.
