My family and I (there are three of us with only two of driving age, my daughter is 12) are driving from NJ to CA, staying a week in CA, then driving back. We are giving ourselves four days to drive out and four to drive back (we are only making two designated stops along the way). My first question is will four days be enough time to make the drive? My next question is about the car we drive. I have an Nissan Xterra with 34,000 miles on it; would it be smart to take it or rent a car? I am getting some good prices on Chevy Trailblazers and Ford Explorers. If I am to rent a car what are some good rental companies to go with and should I spring for the extra insurance? I already checked with my insurance and they said I would be covered the same as I am covered in my personal car (which is full coverage). Any help would be great thanks!
