Thanks all for the responses...
currently I have neither solar panels nor generator, still have the stock converter on my trailer, and am just trying to improve things.
I have heard that an inverter(with a charger) would be better than the stock converter, and am weighing the cost/benefits of solar over a generator, so when I saw an Inverter generator, it piqued my interest and wanted to know more about it.
I think in the short term, an inverter generator would be less expensive than purchasing panels + misc hardware, inverter, and having it all installed.
