Never. I’ve gotten along for 50+ years mostly with just a small (quiet) portable generator. I rarely want AC and even more rarely camp in commercial CGs.
I put 200 w of solar on my current RV. It is useless because I need the power to run the heater in cold months and at my latitude the sun is only up a few hours and at such a low angle the solar adds zip.
I am considering an exhaust pipe extension for the generator my current RV has to hopefully quiet it for those rate occasions I want it and others are camped nearby. But for my next trip starting next month I’m just replacing the 12 v batteries with 6 v golf cart batteries. I can get by a couple of nights without charging with them.
