My friend and I want to take our kids on an RV trip in ~8-9 days from Birmingham, AL to California (preferably LA, as my daughter only cares that she sees the "Hollywood" sign, haha) and back. I have no idea where to start, as neither of us have ever taken or planned a trip like this before! Any advice would be MUCH appreciated. Kids are ages 5,9,9, and 10....thanks!!
