I'm making the move from Phoenix, AZ to Redmond, WA. I'm driving a U-haul that's towing a car behind it. I'm interested in getting to WA quickly, but as this is my first big road trip using a U-haul I am worried about the terrain/elevation. Mapquest suggests going straight through Utah making your way northwest (23 hours, 1555 miles), google maps suggests going through Las Vegas then Utah (27 hours, 1570 miles), AAA recommends going through Sacramento, CA (23 hours, 1520 miles). It seems going through California would be the best route. I'm just worried that it may be a bit more mountainous than the other two routes, and am also concerned about traffic in Cali. Any help/info would be really appreciated!
