Would it keep your batteries charged.. I doubt a 100 watt panel would but you need to do some math, a whole lot of it in fact
First add up your power use.. Lights, if traditional lamp bulbs a 1141 draws about 19 watts, or 1.5 amps. a 1156 about 2 amps (you will need to look up or measure the actual amprage) so for every hour you need 1.5 or 2 amp hours of power to operate
Also everything else, TV, Water pump. You need to knwo the draw, Easiest way to figure out your daily draw is with something like a Tri-Metric battery monitor. (In this case run a day without shore or solar, run completly off battery)
Now multiply by about 1.25, then divide by the number of hours of sun, then multiply by 2.0 (Since you only get about half the rated power out of most panels) and you are cloe to your solar needs. you can fine tune from there.
