Similar to the other answers, we did a road trip from Denver to Madison, WI. ABRP is the best first step to plan the complete route with the stops and how much to charge at each stop. In general, our state of charge was a little better than the ABRP projection.
For each charging stop, check PlugShare to see how much success folks recently had at the charging station. Also, look for close-by fall back chargers just in case. PlugShare also provides the street address of the charging stations which is great for the next step.
For each leg of the trip, use Alexa to navigate to the charging station and let it know that it is a charging station so that the truck knows to condition the batteries for the charge as you arrive. "Alexa - Navigate to the charging station at 123 Main Street Anytown AnyState". It may come back with several choices, pick the right one and you are good to go.
Some of the reports of ElectrifyAmerica stations not working did not hold true for us where they worked fine for us but someone an hour earlier could not charge.
We did have 2 instances where the truck would not sync to the EA station and a hard reset (press & hold the left steering wheel button and the hazard button at the same time) resolved it.
Along the I-80 corridor, there were plenty of CCS (fast charging) stations. However, turning north to WI, level 2 or worse was the best we could do and that got a little stressful. I believe CA is much better for charging availability.
