CrashCash,
Defintely get the app for Plugshare. There are several sites for finding charging stations but Plugshare is by far the best. Recommend you get join Chargepoint so you can use their stations. Some Chargepoint stations are free, some aren't and some are free for a certain charging time and after that you will pay. But something I will say about Chargepoint stations is I have yet to find one that would not allow me to charge at full power. (6300 watts) But also look at what kinds of EVSE's are around you or where you want to travel to. I am not a fan of the Blink network at all but if you travel in TN they are frequently the only option. Get whatever accounts you need to go where you want to go. If you think you may need to charge at campgrounds then get the app for RV Parky. Just have the plug for a NEMA 14-50 and you have 50 amps of charging power available. Your charging speed will be the same as any J1772 plug.
On Plugshare it will often say what brand of EVSE is at a particular site. A GE Wattstation will not work with a Zero because they require authentication with your BMS. Learn what a GE Wattstation looks like and know before you go. Whole Foods have GE Wattstations at them.
I have charged successfully with Eaton, Chargepoint, Blink, Nissan, Clipper Creek, Leviton, and Aerovironment EVSEs. May be forgetting others but the GE systems are the only ones I can't charge at.
