Divert up to I-20 via Hattiesburg, AL. That's our path and we've done it a lot. We tried something different this time taking US 82 across but I can't recomend it. Until you get to Paris the road quality is good for 20 miles then bad and rutted. Past Paris it is good. US 287 on the other side of DFW is the way to go, fast, good road and drops you close to CO.
