If your to worried about the truck makin the trip why not just rent a trailer and tow it back to Dallas? That way at least your not stuck on the side of the road for God knows how long....You will have plenty of time to drive it once you get it and fix it up....The key is to get it home SAFELY so you can drive it.

Old Sub...Amarillo is about a 7-8 hour drive from the DFW metroplex....
