We have been on the route from 98 (santa rosa) to I-10 and it is fine, but 2 lane.
We live in the foley area, and travel 65 when coming down from Montgomery, If you are concerned you could do that and cut across 10 and then down 331, but it seems like a much longer route. The only concern might be a low overpass since you go through some smaller towns. If you have a truckers atlas, it will tell you where they are in each state.
Hope that helps some!
