I'm trying to drive from Baton Rouge,LA to Livermore, Ca Any suggestion?

This is a 32 hour trip.  So if you want to do it in 3 days that means 10+ hours a day.  Three days could be

Baton Rouge to Odessa (Texas)(11 plus hours)

Odessa to Phoenix (10 hours)

Phoenix to Livermore (10 hours)

I think I would not want to do such long days. I might split it into four or five days and stop at San Antonio (6 hours), El Paso (8 hours), and Phoenix (7 hours) before I went to Livermore - this still leaves a 10+ hour day in California to get to Livermore.

I'd recommend doing the drive over at least 4 days.  8 hours per day of driving is about the maximum of what can be reasonably expected of any person.  You don't mention if you'll have anyone else with you - if so, then maybe you can do it in 2-3 days if you split the driving so that each person drives no more than 8 hours per day.  

I'd do it as follows: Day 1: Baton Rouge - Oklahoma City (via Shreveport and Dallas); Day 2: Oklahoma City - Albuquerque; Day 3: Albuquerque - Las Vegas (along I-40 to Kingman and then to U.S. 93) and Day 4: Las Vegas - Livermore (via Barstow, Mojave, Bakersfield and Modesto.
