In a week, a few friends and I will travel from the bay area to the Death Valley, Las Vegas, the Grand Canyon, LA, and then back to the bay area. We plan to take about 14 days for this. We will have five people in half of the trip and four or three in the other half.
I have a 1.5-year Toyota Prius with 13000 miles on it. I'm wondering if it's better to drive my Prius (for fuel efficiency and familiarity with the car) or to rent an SUV (for being able drive on some of the rough roads [are there any in this route?] and reliability).
Three of us might drive in turn. Would renting make this simpler (in terms of insurance and liability)? We are US-licensed drivers with insurance on our regular vehicle. Do we need to purchase additional insurance (either renting or driving my own)?
