That’s one of them there was another I saw too but I’ll have to look it up later. The cheapest version of the trailer doesn’t include the power for helping tow but it is an option
The Pebble Flow can be maneuvered under its own power to the charging stall.Yeah I don't think they could currently be charged at most EV chargers as they are too big and you don't want to try to back that into a car spot. When you get where you're going they've said it should be able to charge up slowly at RV hookups + solar in a weekend back to full. I believe one of the interviews I saw even talked about most of the time these RVs just sit there doing nothing so they were trying to look into how you could basically treat it as a battery backup for your house and let your house charge and discharge from it as needed.
