@RussC, where are you located and where's your trip from/to?
I find trip planning actually fun. If you're not in a hurry and want to be a tourist, try combining L1/L2 charging with visiting points of interest (e.g., Grand Canyon) and be sure to carry your own EVSE with a handful of adapters and a long #10 or #12AWG extension cord. Electricity is everywhere.
I find Plugshare invaluable, and be sure to join them and leave comments on the app whenever you stop and charge. I've successfully used ABRP and a few times it provided options 'better' than my own, especially off the beaten track.
Always have at least one or more alternatives for every distant charging destination. On a road trip we try to never stop anywhere (especially for meals) without actually plugging the car in, the goal being to never ever have to wait for the car to charge.
Best of all, treat your road trip as a fun puzzle and adventure and not a nail-biting marathon. (Disclaimer: my wife doesn't necessarily share this opinion)
PS. To answer the OP's original question, I find my navigator's inability to play "what if's" with our Kona's Nav while I'm driving to be frustrating (to say the least).
