What route should i take home. Los Angeles to The Bay Area?

405 to the 5 to 152 (Pachico P) to the 101. It's freeway all the way. Pachico P is not as steep a grade as Questa P on the 101. Just remember that when you are pulling a trailer you are restricted to 55 MPH just like the semi trucks. Watch your speed around Harris Ranch (highway 198) , it's patrolled by aircraft.
