My 2 cents worth
Have had 2 solar panels at 160 watts each and 6 12v agm batteries for almost 2 years. Main use has been when the unit is in storage. Don't need solar when staying in any campground with power, or when staying just one night without power and driving on the next day. Extra batteries is what gets us through the night(s) with residential refrigerator (remember to turn your ice maker off when stopped for the night). I figure that if we really insist on being able to boondock indefinitely, we would need 2 more panels in order to minimize the generator use. Even then it is hard to justify adding panels since we do like to run the A/C/heat pump, microwave, blowdrier, central vac, & icemaker/automatic defrost if needed, and that means running the generator some anyway (like the noise or not).
