Just a (hopefully amusing) piece of anecdata: we have a squaredrop trailer, with a set of solar panels to power/charge the 12v marine battery and a pair of Jackery power banks. Most of our camping is done in the eastern woodlands: WV, PA, VA, etc.
There is so much tree cover all the time. Some days, even though it's mostly or fully sunny, we're almost always at the end of some disused fire road on the wrong side of a mountain, and we're lucky to get a couple of % back from all-day charges. I'm considering one of those water-powered turbines, since it'll work all night long as well.
Do eastern fire roads often feature fast moving creeks? I kid.
Are you able to tilt your solar panels? If they are lying flat on your roof, you won't get much power from them.
Speaking as someone that has spent the last three summers off-grid in a forest, in your situation, I'd add the ability to tilt the solar panels, reduce power consumption, and get a multi-fuel (propane and gas) inverter generator along with a propane tank. The inverter generator is a lot quieter, smaller, and lighter than generators. I don't need much power and mostly use the generator for the microwave and occasional topping off the batteries.
