As others have said call ahead to reserve a “50 Amp” site. At peak RV travel times or in snowbird country, expect to pay the daily rate if you displace a camper. I have paid as much as $60 flat-rate and $20 an hour at different sites (cheaper than a tow). At low demand times you might get more reasonable rates and better availability. Mid-day access seems the most available. Check on Plugshare and filter for NEMA 14-50 connector sites to get recent site reports. I have used ClipperCreek, EVSEupgrade, OpenEVSE, and Juicebox EVSE units on trips. I have seen others use ChargePoint, Siemens, AeroVironment, Tesla, Jesla, and Bosch. All have worked well.
