The camper carries 200W of solar on the roof to keep the batteries up. It has been a bit disappointing. We usually are camped in some level of shade, and the panels don't aim straight at the sun, so we seldom see more than 100W of output. But, shore power is available most of the time, and we have a small Generac IQ2000 generator (quieter than a Honda) that we use if we are dispersed enough.
