You're going to go through some mountain passes on that drive. And using the air conditioning. If you take the Clarity start the trip with a full charge and start out in HV and stay in HV the entire trip if possible, because even in HV it is reported that some of the EV charge will be "sipped" by the system as needed on a long drive especially during hill climbs. So don't be alarmed if you see the EV range slowly going down during the drive even though you are driving in HV. And remember after each stop at a rest stop, gas station, restaurant etc. when starting out again to push the HV button otherwise it will revert back to EV and you will use up your EV charge in no time when you get back onto the 70 mph interstate. Climbing hills with 0 EV range is no fun.
Also be sure to bring your charge cable with you in case you are able to charge at your hotel. Even without your cable you could charge at Chargepoint and other locations if needed. If in spite of all this you run out of EV range and have a hill climb coming up in say fifty miles, you will probably want to use Charge Mode (press HV button and hold it) which will charge up the battery to a little over 50%. Charge Mode is normally not a useful feature because it is not an efficient way to charge the battery, but it's a lot better than trying to climb a hill with 0 EV range.
And speaking of range, as you know the Clarity has a small fuel tank so plan for more frequent gas stops. It won't be a problem unless you forget to keep on top of it. And if you do use charge mode at any time that will be burning extra gasoline so be sure to factor that in when planning fuel stops.
I'm not trying to discourage you, people have driven trips like this I am just passing along the tips they say to follow to make the trip more enjoyable.
