Obviously, how much solar power you end up needing depends greatly on how much energy you need to "replenish" back into your battery.
If the system is limited to a single typical RV battery, then you're limited to around 50 Amp-hours a day, maybe a little more if you let battery run down lower. If so, that's only around 600 watt-hours per day of useable energy, which isn't that much.
I expect that once most owners have a system up and running, they find they'll use it more than originally planned. For that reason I would engineer components and wiring as if you were going to replenish a couple of large batteries from 50% depth of discharge at a minimum.
