For the cost of laptops these days (in the $300 range) you might consider a 15" laptop and charge that with a small 100 - 200 watt inverter that plugs into a cigarette lighter receptacle. You can play a DVD on the laptop.
Your RV will use about 35 AH daily to run just the CO meter, propane detector and refrigerator. Lights and everything else is on top of that.
100 watts will make between 28 and 35 AH daily, depending on conditions, and full sun. You will not have very much reserve. But you do not require the battery to be full daily, just not as low as the day before. It will recharge the day after you stop camping. . .
If I had $200 to spend, I would rather buy a $13 PWM controller and a 100 watt panel, than to spend it on a MPPT controller, and no solar panel expansion kit.
The link above is a wonderful price on panels. You might want to check this link too, compare shipping costs, ect.
