It all depends on the type of camping you do. We normally make it thru a long weekend on our batteries. If we camp during July and August we bring our genny to be able to run our AC etc. Otherwise we run on propane and batteries. It doesn't take the genny long to charge the batteries. with solar you still have to deal with cloudy days and your batteries won't be enough to run the Air conditioner. As far as I'm concerned, bring your genny. It's more reliable than the sunlight.
Just my $.02 FWIW
Safe travels and all the best.
