To charge the battery while the boat is running you would need to install solar panels which depending on your boat might not be an option. Typically most people run multiple batteries in parallel to run their appliances/equipment. Since you'll be running a fridge I recommend a deep cycle battery like the Bright Way Deep Cycle RV or Marine Battery - AGM - 12V - 110 Ah - Group 30H Item # BRW44FR. Deep cycle batteries are designed to provide a steady amount of current over a long period of time and can be repeatedly discharged and recharged without causing damage or shortening their life.

A 3000 watt inverter like the Go Power Industrial Pure Sine Wave Inverter Charger - 3,000 Watts - 100 Amps - 12V Item # 34275013 is a bit overkill for a small fridge. I recommend the Power Inverter 1000 Watts with Three AC Receptacles Item # WC3720 as it has three receptacles to power your fridge and two other appliances. You'll most likely need some extra 6AWG wire to run it to your battery bank.

I recommend using the Hopkins Endurance 5th Wheel/Gooseneck 90-Degree Wiring Harness w/ 7-Pole Connector - 6' Long #HM41158. It mounts in the truck bed sidewall, tailgate post or the wheel well. It will plug into your factory wiring.

You should have no issue hooking up your trailer battery to the same 12 volt wire that charges your breakaway battery. You will just need to make sure that you do not drain the batteries when they are being used. An isolator or diode is not needed…

For DC electricity, I can help you out. You can run a 10 gauge wire like #10-1-1 sold by the foot from a 6-way or 7-way connection from the 12V to a deep cycle 12V battery and then run the battery to a ground on the trailer. You can use a solenoid…

You'll simply need to wire your two Bright Way Deep Cycle RV or Marine Battery #BRW34FR in parallel. This links the batteries together so that the voltage stays the say but the amp hour ratings will be added together. From there you should be…
