Irene and I near exclusively boon dock with our 2007 2350 in various national parks and other public lands where there are no hook-ups. We will travel for 3 to 4 weeks at a time and will stay in a place with hook-ups maybe for 3 nights the entire trip.
Because we tow a Jeep, our PC stays put at the camp site while we sight-see and day-hike. Doing so, we need to dump and replenish our water every 3rd day and need to run our generator daily for one hour using our 40 amp step charger as shown
HERE.
Most 2100 owners do not tow another vehicle. If you plan to setup camp and stay put, then I would agree with the other comments. But if you break camp daily and go sight-seeing and such, you will quickly learn that driving your PC daily keeps your batteries charged well. And if a dump station is along the way, then you simply dump & replenish as needed.
So it all depends on whether you stay put at your campsite, or get in your PC and travel about while at your destinations.
About solar panels... Keep in-mind that they do little to no good if you are a camp-site shade seeker. Since we are shade seekers, I didn't feel solar technology would benefit us enough so I decided against it. If you are a desert fox camping often in the desert without shade, that would surely change things.
