Don't sweat it.
We are heading down to our place in Bahia de Los Angeles for a few days then on to Loreto, a couple of weeks in La Paz with an overnight in Cabo, back up to Punta Chivato for a few nights, stopping for another week in Bahia de Los Angeles, overnight in Estero Beach and then, sadly enough, back into the border line to finish my last year of work before moving to La Paz.
Since you state you are day time driving, especially through the northern corridor, you should be fine.
Of course, there are no absolutes in life.
