Electric RVs would have tens of kwh of battery storage. You'd be able to run heating, AC, warm water, dishwashers, whatever for quite some time without charging. If you have a full charge and you really need 4KW, a 60kwh battery would last for 15 hours. That would be a really tiny battery for an RV of course. You'd likely want something a bit bigger. Maybe a 100kwh (25 hours) or even more. You get my point, it's not going to be an issue for most people. You can still plug it in or drive to the fast charger once a day or conserve a bit of power and maybe don't run the AC 24/7 on full blast.
