Inverter, Solar, and Other Power Recommendations

"I wouldn't mind having portable solar panels that I attach directly to the battery to charge."

Panels send power to the charge controller not directly to the batteries. You want to stay in camp to watch over your portable panels, fine. Mounted on the roof you can go as you please. Leaks from solar panels? Unlikely if properly installed. Portable panels cost more than roof panels. My wind resistance, as in reduced MPG, is zero and they are right up front on the TT.
