I have three routes to choose from: 1) I-40 to I-30 to I-20 to I-10, 2) I-85 to Atlanta then I-20 to I-10, I-85 to I-65 to I-10. Routes #1 I have to go through Chattanooga, Knoxville, Nashville, Memp...
I would take 40 all the way to AZ. The last big mess we had was in memphis but that was summer before last. Probably still there but not that big a hassle. Once in AZ depends on where in baja you plan to go. East LA or the Baja AZ? If bound and determined head south out of albuquerqe on 25 to hatch and over to 10 or take some scenic down eastern az from 40. Some hills to pull but you should not have problems see MHs on them all time. Big thing is where do you want to get to?
