I agree with this. I’ve had solar panels on three rigs and they’re great. I found no need for a standard gas generator at all.With today's solar generators, there's no need for the traditional gas powered generator. Do yourself and your camping neighbors a favor and go the Li PO4 route for power. More than enough to do everything you want without the noise.
I opted for a DC to DC charger on my current van conversion though, and have found that it’s so efficient that I don’t need solar panels at all. It has a solar plug in with built in controller if I ever want to add solar panels at a later time. The deep cycle AGM house battery powers the old school and inefficient 12 volt refrigerator and furnace fan, as well as the LED interior lights surprisingly well because the DC to DC charges it so quickly.
