First you have to do an energy audit. You need to know what is drawing power and how much. You mentioned a tracking device, you also have parasitic draws, radio, CO, smoke, propane detector. Some of these are hard wired in. No fuse. You said you have a 100W controller and 240W panel. Is that correct? If so you may want to upgrade that.
If you dont have a battery monitor, that would be a good investment too. You will be able to monitor that state of charge on your batteries. I have a Victron BMV-712 bluetooth monitor. I can keep an eye on the batteries from the house 100' away. Could be handy for you if your RV is in storage. Pull up out front and check the batteries without leaving your car. Victron also makes a Bluetooth MPPT controller that you can also monitor remotely. I have a Victron Smart Solar 100/30 MPPT controller. I should have got the 100/50 model.
