If it needed to for you to make your trip successfully, but it appears you might be picturing "run it down to almost empty, charge up to full" the way you do with a gas vehicle. In general, you will start your long trip with 90% to 100% charge, run down to around 10-20% charge, then stop and charge back up to about 50-60% charge (unless there is a huge gap between chargers).
You will stop about every couple hours or so in a road trip in a Tesla, but charging from 10-15% to 50-60% will result in a stop basically long enough to use the restroom and buy some snacks, 15-20 minutes or so.
